116 It is a way to monitor the tail of a file which is growing
118 (The behavior is similar to the "tail \-f" command.)
119 To stop waiting for more data, enter the interrupt character (usually \(haC).
122 you can also use \(haX or the character specified by the \-\-intr option.

146 Go to the line containing byte offset N in the file.
148 If a left curly bracket appears in the top line displayed
149 on the screen,
150 the { command will go to the matching right curly bracket.
151 The matching right curly bracket is positioned on the bottom
152 line of the screen.
153 If there is more than one left curly bracket on the top line,
154 a number N may be used to specify the N-th bracket on the line.
156 If a right curly bracket appears in the bottom line displayed
157 on the screen,
158 the } command will go to the matching left curly bracket.
159 The matching left curly bracket is positioned on the top

250 That is, if the search reaches the end of the current file
251 without finding a match, the search continues from the first line of the
252 current file up to the line where it started.
253 If the \(haW modifier is set, the \(haE modifier is ignored.
255 The next character is taken literally; that is, it becomes part of the pattern
256 even if it is one of the above search modifier characters.
259 Search backward in the file for the N-th line containing the pattern.
260 The search starts at the last line displayed
261 (but see the \-a and \-j options, which change this).
263 Certain characters are special as in the / command:
266 Search for lines which do NOT match the pattern.
269 That is, if the search reaches the beginning of the current file

287 current file up to the line where it started.
294 Repeat previous search, for N-th line containing the last pattern.
295 If the previous search was modified by \(haN, the search is made for the
296 N-th line NOT containing the pattern.
297 If the previous search was modified by \(haE, the search continues
298 in the next (or previous) file if not satisfied in the current file.
299 If the previous search was modified by \(haR, the search is done
301 There is no effect if the previous search was modified by \(haF or \(haK.
303 Repeat previous search, but in the reverse direction.
306 The effect is as if the previous search were modified by *.

321 this clears all search matches marked in the status column.
323 Display only lines which match the pattern;
324 lines which do not match the pattern are not displayed.
327 While filtering is in effect, an ampersand is displayed at the
328 beginning of the prompt,

351 in the name.
353 The filename is inserted into the command line list of files
355 If the filename consists of several files, they are all inserted into
356 the list of files and the first one is examined.
357 If the filename contains one or more spaces,
358 the entire filename should be enclosed in double quotes
359 (also see the \-" option).
365 Examine the next file (from the list of files given in the command line).
366 If a number N is specified, the N-th next file is examined.
368 Examine the previous file in the command line list.
369 If a number N is specified, the N-th previous file is examined.
371 Examine the first file in the command line list.
372 If a number N is specified, the N-th file in the list is examined.
374 Remove the current file from the list of files.
376 Go to the next tag, if there were more than one matches for the current tag.
377 See the \-t option for more details about tags.
379 Go to the previous tag, if there were more than one matches for the current tag.
381 Search forward in the file for the N-th next OSC 8 hyperlink.
383 Search backward in the file for the N-th previous OSC 8 hyperlink.
385 Jump to the currently selected OSC 8 hyperlink.
387 Prints some information about the file being viewed,
389 and the line number and byte offset of the bottom line being displayed.
390 If possible, it also prints the length of the file,
391 the number of lines in the file
392 and the percent of the file above the last displayed line.
394 Followed by one of the command line option letters (see OPTIONS below),
395 this will change the setting of that option
396 and print a message describing the new setting.
397 If a \(haP (CONTROL-P) is entered immediately after the dash,
398 the setting of the option is changed but no message is printed.
399 If the option letter has a numeric value (such as \-b or \-h),
401 a new value may be entered after the option letter.
403 the current setting is printed and nothing is changed.
405 Like the \- command, but takes a long option name (see OPTIONS below)
407 You must press ENTER or RETURN after typing the option name.
408 A \(haP immediately after the second dash suppresses printing of a
409 message describing the new setting, as in the \- command.
411 Followed by one of the command line option letters
412 this will reset the option to its default setting
413 and print a message describing the new setting.
414 (The "\-+\fIX\fP" command does the same thing
415 as "\-+\fIX\fP" on the command line.)
418 Like the \-+ command, but takes a long option name
421 Followed by one of the command line option letters,
422 this will reset the option to the "opposite" of its default setting
423 and print a message describing the new setting.
426 Like the \-!\& command, but takes a long option name
430 Followed by one of the command line option letters,
431 this will print a message describing the current setting of that option.
432 The setting of the option is not changed.
435 Like the _ (underscore) command, but takes a long option name
437 You must press ENTER or RETURN after typing the option name.

457 Invokes an editor to edit the current file being viewed.
458 The editor is taken from the environment variable VISUAL if defined,
461 See also the discussion of LESSEDIT under the section on PROMPTS below.
463 Invokes a shell to run the shell-command given.
464 A percent sign (%) in the command is replaced by the name of the
466 A pound sign (#) is replaced by the name of the previously examined file.
467 "!!" repeats the last shell command.
469 If a \(haP (CONTROL-P) is entered immediately after the !,
470 no "done" message is printed after the shell command is executed.
471 On Unix systems, the shell is taken from the environment variable SHELL,
473 On MS-DOS, Windows, and OS/2 systems, the shell is the normal command processor.
475 Similar to the "!" command, 
476 except that the command is expanded in the same way as prompt strings.
477 For example, the name of the current file would be given as "%f".
480 Pipes a section of the input file to the given shell command.
481 The section of the file to be piped is between the position marked by
482 the letter and the current screen.
483 The entire current screen is included, regardless of whether the
484 marked position is before or after the current screen.
486 If <m> is \&.\& or newline, the current screen is piped.
487 If a \(haP (CONTROL-P) is entered immediately after the mark letter,
488 no "done" message is printed after the shell command is executed.
490 Save the input to a file.
491 This works only if the input is a pipe, not an ordinary file.
494 Run a shell command to open the URI in the current OSC 8 hyperlink,
496 To find the shell command,
497 the environment variable named "LESS_OSC8_xxx" is read, 
498 where "xxx" is the scheme from the URI (the part before the first colon),
499 or is empty if there is no colon in the URI.
500 The value of the environment variable is then expanded in the same way as 
501 prompt strings (in particular, any instance of "%o" is replaced with the URI)
503 The standard output from the handler is an "opener" shell command 
504 which is then executed to open the URI.
509 If the URI begins with "#", the remainder of the URI is taken to be 
510 the value of the id parameter in another OSC 8 link in the same file,
513 If the opener begins with the characters ":e" followed by 
515 then instead of running the opener as a shell command,
516 the specified filename is opened in the current instance of
520 In a simple case where the opener accepts the complete URI
521 as a command line parameter, the handler may be as simple as
527 In other cases, the URI may need to be modified, so the handler
528 may have to do some manipulation of the %o value.
530 If the LESS_OSC8_xxx variable is not set, the variable LESS_OSC8_ANY is tried. 
532 links using the "xxx" scheme cannot be opened. 
533 However, there are default handlers for the 
536 which should work on systems which provide the
538 command and a shell with syntax compatible with the Bourne shell
541 set LESS_OSC8_file to "-" to indicate that the default value 
544 The URI passed to an OSC8 handler via %o is guaranteed not to contain any single quote
547 The handler should take care to appropriately quote parameters in the opener command,
548 to prevent execution of unintended shell commands in the case of opening
550 Also, since the handler command is expanded like a command prompt,
553 (see the PROMPTS section for details).
556 When the "Waiting for data" message is displayed,
557 such as while in the F command, pressing \(haX
563 to think that the file ends at the current position,
564 so it may be necessary to use the R or F command to see more data.
565 The \-\-intr option can be used to specify a different character
567 This command works only on systems that support the
572 the interrupt character (usually \(haC) can be used instead.
578 is running, via the "\-" command.
584 the abbreviation is unambiguous.
590 the remainder of the name may be in either case.
593 Options are also taken from the environment variable "LESS".
607 On MS-DOS and Windows, you don't need the quotes, but you should 
608 be careful that any percent signs in the options string are not
611 The environment variable is parsed before the command line,
612 so command line options override the LESS environment variable.
613 If an option appears in the LESS variable, it can be reset
614 to its default value on the command line by beginning the command
617 Some options like \-k or \-D require a string to follow the option letter.
618 The string for that option is considered to end when a dollar sign ($) is found.
623 If the \-\-use-backslash option appears earlier in the options, then
626 If the \-\-use-backslash option is not in effect, then backslashes are
628 in the option string.
630 This option displays a summary of the commands accepted by
632 (the same as the h command).
633 (Depending on how your shell interprets the question mark,
634 it may be necessary to quote the question mark, thus: "\-\e?".)
636 By default, forward searches start at the top of the displayed screen
637 and backwards searches start at the bottom of the displayed screen
638 (except for repeated searches invoked by the n or N commands,
639 which start after or before the "target" line respectively;
640 see the \-j option for more about the target line).
641 The \-a option causes forward searches to instead start at
642 the bottom of the screen
643 and backward searches to start at the top of the screen,
644 thus skipping all lines displayed on the screen.
647 to start just after the target line, and all backward searches
648 to start just before the target line.
649 Thus, forward searches will skip part of the displayed screen
650 (from the first line up to and including the target line).
651 Similarly backwards searches will skip the displayed screen
652 from the last line up to and including the target line.
653 This was the default behavior in less versions prior to 441.
655 Specifies the amount of buffer space
659 (unless the file is a pipe; see the \-B option).
660 The \-b option specifies instead that \fIn\fP kilobytes of
663 the entire file can be read into memory.
667 If a large amount of data is read from the pipe, this can cause
669 The \-B option disables this automatic allocation of buffers for pipes,
671 (or the amount of space specified by the \-b option)
672 is used for the pipe.
673 Warning: use of \-B can result in erroneous display, since only the
674 most recently viewed part of the piped data is kept in memory;
678 Causes full screen repaints to be painted from the top line down.
680 full screen repaints are done by scrolling from the bottom of the screen.
685 The \-d option suppresses the error message
686 normally displayed if the terminal is dumb;
688 such as the ability to clear the screen or scroll backward.
689 The \-d option does not otherwise change the behavior of
693 Changes the color of different parts of the displayed text.

716 The highlight enabled via the \-w option.
718 The text in a search result which matches
719 the first through fifth parenthesized sub-pattern.
722 is built with one of the regular expression libraries
735 The uppercase letters and digits can be used only when the \-\-use-color option is enabled.
737 the uppercase letter takes precedence. 
739 So if both "s" and "E" are given a color, the "E" color applies
740 to error messages, and the "s" color applies to other standout text.
741 The lowercase letters refer to bold and underline text formed by 
742 overstriking with backspaces (see the \-U option) and to non-content
744 but not to text formatted using ANSI escape sequences with the \-R option
745 (but see the note below for different behavior on Windows and MS-DOS).
748 the normal format change and the specified color should both be used.
750 the green color has replaced the usual underline formatting.
756 the first character specifies the foreground color and 
757 the second specifies the background color as follows:
775 The corresponding uppercase letter denotes a brighter shade of the color.
779 If either character is a "-" or is omitted, the corresponding color 
783 where the first integer specifies the foreground color and 
784 the second specifies the background color.
791 the corresponding color is set to that of normal text.
793 A 4-bit or 8-bit color string may be followed by one or more of the
794 following characters to set text attributes in addition to the color.
804 On MS-DOS and Windows, the \-\-color option behaves
807 The bold (d and *) and blinking (l and &) text attributes
808 at the end of a color string are not supported.
816 the number is not interpreted as an "CSI 38;5" color value as described above,
827 To avoid confusion, it is recommended that the equivalent letters rather than numbers
833 Only a limited set of ANSI escape sequences to set color in the content work correctly.
836 The \-Da option makes the behavior of \-\-color 
840 allowing "CSI 38;5" color sequences in the content
841 work by passing them to the terminal (only on Windows 10 and later; on
842 earlier Windows systems, such sequences do not work regardless of the setting of \-Da).

849 By default, the only way to exit
851 is via the "q" command.
855 to automatically exit the first time it reaches end-of-file.
859 Also suppresses the warning message when a binary file is opened.
869 if the entire file can be displayed on the first screen.
873 will highlight ALL strings which match the last search command.
874 The \-g option changes this behavior to highlight only the particular string
875 which was found by the last search command.
878 to run somewhat faster than the default.
880 The \-G option suppresses all highlighting of strings found by search commands.
884 the screen is repainted in a forward direction instead.

903 The screen line may be specified by a number: the top line on the screen
904 is 1, the next is 2, and so on.
905 The number may be negative to specify a line relative to the bottom
906 of the screen: the bottom line on the screen is \-1, the second
907 to the bottom is \-2, and so on.
908 Alternately, the screen line may be specified as a fraction of the height
909 of the screen, starting with a decimal point: \&.5 is in the middle of the
910 screen, \&.3 is three tenths down from the first line, and so on.
911 If the line is specified as a fraction, the actual line number
912 is recalculated if the terminal window is resized.
913 If the \-\-header option is used and the target line specified by \-j
914 would be obscured by the header, the target line is moved to the first
915 line after the header.
916 While the \-\-header option is active, the \-S option is ignored,
917 and lines longer than the screen width are truncated.
920 If any form of the \-j option is used,
922 begin at the line immediately after the target line,
923 and repeated backward searches begin at the target line,
925 For example, if "\-j4" is used, the target line is the
926 fourth line on the screen, so forward searches begin at the fifth line
927 on the screen.
929 always begin at the start or end of the current screen respectively.
932 Displays a status column at the left edge of the screen.
933 The character displayed in the status column may be one of:
936 The line is chopped with the \-S option, and 
937 the text that is chopped off beyond the right edge of the screen
938 contains a match for the current search.
940 The line is horizontally shifted, and
941 the text that is shifted beyond the left side of the screen
942 contains a match for the current search.
944 The line is both chopped and shifted,
945 and there are matches beyond both sides of the screen.
947 There are matches in the visible part of the line
948 but none to the right or left of it.
950 The line has been marked with the corresponding letter via the m command.

1091  \-Pm changes the medium (\-m) prompt.
1092  \-PM changes the long (\-M) prompt.
1093  \-Ph changes the prompt for the help screen.
1094  \-P= changes the message printed by the = command.
1095  \-Pw changes the message printed while waiting for data (in the "F" command).

1102 the terminal bell is not rung
1103 if an attempt is made to scroll past the end of the file
1104 or before the beginning of the file.
1105 If the terminal has a "visual bell", it is used instead.
1106 The bell will be rung on certain other errors,
1108 The default is to ring the terminal bell in all such cases.
1111 the terminal bell is never rung.
1112 If the terminal has a "visual bell", it is used in all cases
1113 where the terminal bell would have been rung.
1116 The default is to display control characters using the caret notation;
1118 (with some exceptions as described under the \-U option).
1119 Warning: when the \-r option is used,
1121 cannot keep track of the actual appearance of the screen
1122 (since this depends on how the screen responds to
1125 such as long lines being split in the wrong place.
1127 USE OF THE \-r OPTION IS NOT RECOMMENDED.
1131 Unlike \-r, the screen appearance is maintained correctly,
1132 provided that there are no escape sequences in the file 
1134 Color escape sequences are only supported when the color
1136 In other words, the beginning of each line is assumed to be
1138 For the purpose of keeping track of screen appearance,
1139 these escape sequences are assumed to not move the cursor.
1141 OSC 8 hyperlinks are sequences of the form:
1145 The terminating sequence may be either a BEL character (\\7) 
1146 or the two-character sequence "ESC \\".
1148 ANSI color escape sequences are sequences of the form:
1152 where the "...\&" is zero or more color specification characters.
1156 by setting the environment variable LESSANSIENDCHARS to the list of
1160 think that characters other than the standard ones may appear between
1161 the ESC and the m by setting the environment variable LESSANSIMIDCHARS
1162 to the list of characters which can appear.
1169 Causes lines longer than the screen width to be
1171 That is, the portion of a long line that does not fit in
1172 the screen width is not displayed until you press RIGHT-ARROW.
1173 The default is to wrap long lines; that is, display the remainder
1174 on the next line.
1175 See also the \-\-wordwrap option.
1177 The \-t option, followed immediately by a TAG,
1178 will edit the file containing that tag.
1180 for example, there may be a file in the current directory called "tags",
1184 If the environment variable LESSGLOBALTAGS is set, it is taken to be
1185 the name of a command compatible with
1187 and that command is executed to find the tag.
1192 The \-t option may also be specified from within
1194 (using the \- command) as a way of examining a new file.
1195 The command ":t" is equivalent to specifying \-t from within
1201 that is, they are sent to the terminal when they appear in the input.
1205 that is, they are handled as specified by the \-r option.
1210 the underlined text is displayed
1211 using the terminal's hardware underlining capability.
1214 the overstruck text is printed
1215 using the terminal's hardware boldface capability.
1216 Other backspaces are deleted, along with the preceding character.
1218 Other carriage returns are handled as specified by the \-r option.
1219 Unicode formatting characters, such as the Byte Order Mark,
1220 are sent to the terminal.
1224 See also the \-\-proc-backspace, \-\-proc-tab,
1227 Displays the version number of
1230 Temporarily highlights the first "new" line after a forward movement
1232 The first "new" line is the line immediately following the line previously
1233 at the bottom of the screen.
1234 Also highlights the target line after a g or p command.
1235 The highlight is removed at the next command which causes movement.
1236 If the \-\-status-line option is in effect, the entire line
1237 (the width of the screen) is highlighted.
1238 Otherwise, only the text in the line is highlighted,
1239 unless the \-J option is in effect,
1240 in which case only the status column is highlighted.
1242 Like \-w, but temporarily highlights the first new line after any
1248 are set at those positions, and then continue with the same spacing as the
1251 The default for \fIn\fP is 8.
1253 Disables sending the termcap initialization and deinitialization strings
1254 to the terminal.
1255 This is sometimes desirable if the deinitialization string does
1256 something unnecessary, like clearing the screen.
1260 the screen is repainted instead.
1261 The \-c or \-C option may be used to repaint from the top of
1262 the screen if desired.
1265 Changes the default scrolling window size to \fIn\fP lines.
1266 The default is one screenful.
1267 The z and w commands can also be used to change the window size.
1268 The "z" may be omitted for compatibility with some versions of
1270 If the number
1274 lines less than the current screen size.
1275 For example, if the screen is 24 lines, \fI\-z\-4\fP sets the
1276 scrolling window to 20 lines.  If the screen is resized to 40 lines,
1277 the scrolling window automatically changes to 36 lines.
1279 Changes the filename quoting character.
1282 Followed by a single character, this changes the quote character to that
1286 Followed by two characters, changes the open quote to the first character,
1287 and the close quote to the second character.
1288 Filenames containing a space should then be preceded by the open quote
1289 character and followed by the close quote character.
1290 Note that even after the quote characters are changed, this option
1296 Specifies the default number of positions to scroll horizontally
1297 in the RIGHTARROW and LEFTARROW commands.
1298 If the number specified is zero, it sets the default number of
1299 positions to one half of the screen width.
1300 Alternately, the number may be specified as a fraction of the width
1301 of the screen, starting with a decimal point: \&.5 is half of the
1302 screen width, \&.3 is three tenths of the screen width, and so on.
1303 If the number is specified as a fraction, the actual number of
1304 scroll positions is recalculated if the terminal window is resized.
1306 When using the "F" command on a pipe,
1308 will automatically stop waiting for more data when the input side of the 
1313 will determine the size of the file 
1314 immediately after opening the file.
1315 Then the "=" command will display the number of lines in the file.
1316 Normally this is not done, because it can be slow if the input file 
1319 Normally, if the input file is renamed while an F command is executing,
1321 will continue to display the contents of the original file despite
1325 will periodically attempt to reopen the file by name.
1326 If the reopen succeeds and the file is a different file from the original
1328 with the same name as the original (now renamed) file),
1330 will display the contents of that new file.
1333 Sets the number of header lines and columns displayed on the screen.
1334 The number of header lines is set to \fIL\fP.
1336 If \fIL\fP is empty or missing, the number of header lines is unchanged.
1337 The number of header columns is set to \fIC\fP.
1339 If \fIC\fP is empty or missing, the number of header columns is unchanged.
1340 The first header line is set to line number \fIN\fP in the file.
1342 the number of the line currently displayed in the first line of the screen
1343 (if the \-\-header command has been issued from within
1345 or 1 (if the \-\-header option has been given on the command line).
1346 The special form "\-\-header=\-" disables header lines and header columns, 
1349 When \fIL\fP is nonzero, the first \fIL\fP lines at the top
1350 of the screen are replaced with the \fIL\fP lines of the file beginning at line \fIN\fP,
1351 regardless of what part of the file is being viewed.
1352 When header lines are displayed, any file contents before the header line cannot be viewed.
1353 When \fIC\fP is nonzero, the first \fIC\fP characters displayed at the 
1354 beginning of each line are replaced with the first \fIC\fP characters of the line,
1355 even if the rest of the line is scrolled horizontally.
1360 will advance to the next line containing the search pattern 
1361 as each character of the pattern is typed in.
1363 Use the character \fIc\fP instead of \(haX to interrupt a read
1364 when the "Waiting for data" message is displayed.
1370 Sets the minimum width of the line number field when the \-N option is in effect 
1372 The default is 7.
1375 because it is shifted to the left or right of the currently
1376 visible screen, the text will horizontally shift 
1377 to ensure that the search match is visible.
1378 This option selects the column in which the first character
1379 of the search match will be placed after the shift.
1381 to the left of the search match.
1383 Alternately, the number may be specified as a fraction of the width
1384 of the screen, starting with a decimal point: \&.5 is half of the
1385 screen width, \&.3 is three tenths of the screen width, and so on.
1386 If the number is specified as a fraction, the actual number of
1387 scroll positions is recalculated if the terminal window is resized.
1392 will read the first \fIn\fP lines to try to find a vim-compatible 
1397 By using a modeline, the file itself can specify the tab stops 
1400 A modeline contains, anywhere in the line, 
1403 possibly followed by the word "set",
1405 If the word "set" is used,
1406 option settings are separated by spaces, and end at the first colon.
1407 If the word "set" is not used, 
1409 The word "set" is required if the program name is "less"
1410 but optional if any of the other three names are used.
1411 If any option setting is of the form "tabstop=\fIn\fP" or "ts=\fIn\fP",
1413 See the \-\-tabs description for acceptable values of \fIn\fP.
1417 scrolling the mouse wheel down moves forward in the file,
1418 scrolling the mouse wheel up moves backwards in the file,
1419 left-click sets the "#" mark to the line where the mouse is clicked,
1420 and right-click (or any other) returns to the "#" mark position.
1421 If a left-click is performed with the mouse cursor on an OSC 8 hyperlink,
1422 the hyperlink is selected as if by the \(haO\(haN command.
1423 If a left-click is performed with the mouse cursor on an OSC 8 hyperlink
1424 which is already selected, the hyperlink is opened as if by the \(haO\(haO command.
1425 The number of lines to scroll when the wheel is moved
1426 can be set by the \-\-wheel-lines option.
1428 and on the Windows version of
1431 Like \-\-mouse, except the direction scrolled
1434 Disables sending the keypad initialization and deinitialization strings
1435 to the terminal.
1436 This is sometimes useful if the keypad strings make the numeric
1439 This option changes the behavior so that if a search string or
1440 file name is typed in, and the same string is already in the history list,
1441 the existing copy is removed from the history list before the new one is added.
1442 Thus, a given string will appear only once in the history list.
1445 Header lines (defined via the \-\-header option) are not assigned line numbers.
1446 Line number 1 is assigned to the first line after any header lines.
1454 Disables the terminal's visual bell.
1456 If set, backspaces are handled as if neither the \-u option 
1457 nor the \-U option were set.
1461 This option overrides the \-u and \-U options, so that display of
1463 If not set, backspace display is controlled by the \-u and \-U options.
1465 If set, backspaces are handled as if the \-U option were set;
1468 If set, carriage returns are handled as if neither the \-u option 
1469 nor the \-U option were set.
1471 This option overrides the \-u and \-U options, so that display of
1473 If not set, carriage return display is controlled by the \-u and \-U options.
1475 If set, carriage returns are handled as if the \-U option were set;
1478 If set, tabs are handled as if the \-U option were not set.
1480 This option overrides the \-U option, so that display of
1482 If not set, tab display is controlled by the \-U options.
1484 If set, tabs are handled as if the \-U option were set;
1487 When quitting, after sending the terminal deinitialization string,
1488 redraws the entire last screen.
1489 On terminals whose terminal deinitialization string causes the
1491 this makes the last screenful of the current file remain visible after
1495 This option changes the character used to mark truncated lines.
1500 Save marks in the history file, so marks are retained
1505 The value is a string of one or more of the characters
1507 Setting any of these has the same effect as typing that
1508 control character at the beginning of every search pattern.
1509 For example, setting \-\-search-options=W is the same as
1510 typing \(haW at the beginning of every pattern.
1511 The value may also contain a digit between 1 and 5,
1512 which has the same effect as typing \(haS followed by that digit
1513 at the beginning of every search pattern.
1514 The value "-" disables all default search modifiers.
1521 Sets the width of the status column when the \-J option is in effect.
1522 The default is 2 characters.
1524 If a line is marked, the entire line (rather than just the status column)
1526 Also lines highlighted due to the \-w option will have
1527 the entire line highlighted.
1528 If \-\-use-color is set, the line is colored rather than highlighted.
1530 This option changes the interpretations of options which follow this one.
1531 After the \-\-use-backslash option, any backslash in an option string is
1532 removed and the following character is taken literally.
1536 The \-D option can be used to change the colors.
1537 Colored text works only if the terminal supports 
1543 Set the number of lines to scroll when the mouse wheel is scrolled
1544 and the \-\-mouse or \-\-MOUSE option is in effect.
1545 The default is 1 line.
1547 When the \-S option is not in use,
1550 The default is to wrap at any character.
1552 A command line argument of "\-\-" marks the end of option arguments.
1557 the remainder of that option is taken to be an initial command to
1561 to start at the end of the file rather than the beginning,
1562 and +/xyz tells it to start at the first occurrence of "xyz" in the file.
1564 that is, it starts the display at the specified line number
1565 (however, see the caveat under the "g" command above).
1566 If the option starts with ++, the initial command applies to
1567 every file being viewed, not just the first one.
1568 The + command described previously
1572 When entering a command line at the bottom of the screen
1573 (for example, a filename for the :e command,
1574 or the pattern for a search command),
1575 certain keys can be used to manipulate the command line.
1578 (Note that the forms beginning with ESC do not work
1579 in some MS-DOS and Windows systems because ESC is the line erase character.)
1581 it with the "literal" character, either \(haV or \(haA.
1584 Move the cursor one space to the left.
1586 Move the cursor one space to the right.
1589 Move the cursor one word to the left.
1592 Move the cursor one word to the right.
1594 Move the cursor to the beginning of the line.
1596 Move the cursor to the end of the line.
1598 Delete the character to the left of the cursor,
1599 or cancel the command if the command line is empty.
1601 Delete the character under the cursor.
1604 Delete the word to the left of the cursor.
1607 Delete the word under the cursor.
1609 Retrieve the previous command line.
1611 it will retrieve the previous command which begins with that text.
1613 Retrieve the next command line.
1615 it will retrieve the next command which begins with that text.
1617 Complete the partial filename to the left of the cursor.
1618 If it matches more than one filename, the first match
1619 is entered into the command line.
1620 Repeated TABs will cycle thru the other matching filenames.
1621 If the completed filename is a directory, a "/" is appended to the filename.
1623 The environment variable LESSSEPARATOR can be used to specify a
1626 Like, TAB, but cycles in the reverse direction thru the matching filenames.
1628 Complete the partial filename to the left of the cursor.
1630 the command line (if they fit).
1632 Delete the entire command line,
1633 or cancel the command if the command line is empty.
1637 Delete the entire command line and return to the main prompt.
1645 You may also change the line-editing keys (see LINE EDITING),
1648 See the
1650 manual page for details about the file format.
1652 If the environment variable LESSKEYIN is set,
1654 uses that as the name of the lesskey source file.
1657 looks in a standard place for the lesskey source file:
1665 in the PATH environment variable.
1670 in the INIT environment variable, and if it not found there,
1672 in the PATH environment variable.
1675 If a key is defined in both a local lesskey file and in the
1676 system-wide file, key bindings in the local file take precedence over
1677 those in the system-wide file.
1678 If the environment variable LESSKEYIN_SYSTEM is set,
1680 uses that as the name of the system-wide lesskey file.
1683 looks in a standard place for the system-wide lesskey file:
1684 On Unix systems, the system-wide lesskey file is /usr/local/etc/syslesskey.
1688 that directory is where the sysless file is found.)
1689 On MS-DOS and Windows systems, the system-wide lesskey file is c:\e_syslesskey.
1690 On OS/2 systems, the system-wide lesskey file is c:\esyslesskey.ini.
1694 (before v582) used lesskey files with a binary format, produced by the
1696 program. It is no longer necessary to use the
1705 opens a file, it first gives your input preprocessor a chance to modify the
1706 way the contents of the file are displayed.
1708 which writes the contents of the file to a different file,
1709 called the replacement file.
1710 The contents of the replacement file are then displayed
1711 in place of the contents of the original file.
1712 However, it will appear to the user as if the original file is opened;
1715 will display the original filename as the name of the current file.
1717 An input preprocessor receives one command line argument, the original filename,
1718 as entered by the user.
1719 It should create the replacement file, and when finished,
1720 print the name of the replacement file to its standard output.
1721 If the input preprocessor does not output a replacement filename,
1723 uses the original file, as normal.
1724 The input preprocessor is not called when viewing standard input.
1725 To set up an input preprocessor, set the LESSOPEN environment variable
1727 This command line should include one occurrence of the string "%s",
1728 which will be replaced by the filename
1729 when the input preprocessor command is invoked.
1734 called the input postprocessor,
1735 which may perform any desired clean-up action (such as deleting the
1737 This program receives two command line arguments, the original filename
1738 as entered by the user, and the name of the replacement file.
1739 To set up an input postprocessor, set the LESSCLOSE environment variable
1741 It may include two occurrences of the string "%s";
1742 the first is replaced with the original name of the file and
1743 the second with the name of the replacement file,
1788 pipe the file data directly to
1790 rather than putting the data into a replacement file.
1791 This avoids the need to decompress the entire file before
1794 An input pipe, instead of writing the name of a replacement file on
1796 writes the entire contents of the replacement file on its standard output.
1797 If the input pipe does not write any characters on its standard output,
1800 uses the original file, as normal.
1802 make the first character in the LESSOPEN environment variable a
1803 vertical bar (|) to signify that the input preprocessor is an input pipe.
1804 As with non-pipe input preprocessors, the command string must contain one
1805 occurrence of %s, which is replaced with the filename of the input file.
1807 For example, on many Unix systems, this script will work like the
1834 the original file is used.
1836 the exit status of the script determines the behavior when the output is empty.
1837 If the output is empty and the exit status is zero, 
1838 the empty output is considered to be replacement text.
1839 If the output is empty and the exit status is nonzero, 
1840 the original file is used.
1843 if LESSOPEN starts with only one vertical bar, the exit status
1844 of the preprocessor is ignored.
1849 In this case, the replacement file name passed to the LESSCLOSE
1854 the input preprocessor or pipe is not used if
1857 However, if the first character of LESSOPEN is a dash (\-),
1858 the input preprocessor is used on standard input as well as other files.
1859 In this case, the dash is not considered to be part of
1860 the preprocessor command.
1861 If standard input is being viewed, the input preprocessor is passed
1863 Similarly, if the first two characters of LESSOPEN are vertical bar and dash
1865 the input pipe is used on standard input as well as other files.
1866 Again, in this case the dash is not considered to be part of
1867 the input pipe command.
1870 There are three types of characters in the input file:
1872 can be displayed directly to the screen.
1882 The LESSCHARSET environment variable may be used to select a character set.
1890 This is the same as ASCII, except characters between 160 and 255 are
1902 This is the EBCDIC analogue of latin1.  You get similar results
1910 Selects the UTF-8 encoding of the ISO 10646 character set.
1911 UTF-8 is special in that it supports multi-byte characters in the input file.
1912 It is the only character set that supports multi-byte characters.
1918 to use a character set other than the ones definable by LESSCHARSET.
1919 In this case, the environment variable LESSCHARDEF can be used
1921 It should be set to a string where each character in the string represents
1922 one character in the character set.
1923 The character ".\&" is used for a normal character, "c" for control,
1928 All characters after the last are taken to be the same as the last,
1933 This table shows the value of LESSCHARDEF which is equivalent
1934 to each of the possible values for LESSCHARSET:
1953 but any of the strings "UTF-8", "UTF8", "utf-8" or "utf8"
1954 is found in the LC_ALL, LC_CTYPE or LANG
1955 environment variables, then the default character set is utf-8.
1957 If that string is not found, but your system supports the
1961 will use setlocale to determine the character set.
1962 setlocale is controlled by setting the LANG or LC_CTYPE environment
1965 Finally, if the
1967 interface is also not available, the default character set is utf-8.
1972 inverting the 0100 bit results in a normal printable character.
1973 Otherwise, the character is displayed as a hex number in angle brackets.
1975 setting the LESSBINFMT environment variable.
1977 the display attribute:
1981 The remainder of LESSBINFMT is a string which may include one
1985 The default if no LESSBINFMT is specified is "*s<%02X>".
1986 Warning: the result of expanding the character via LESSBINFMT must
1989 When the character set is utf-8, the LESSUTFBINFMT environment variable
2002 of how the UTF-8 file is ill-formed.
2004 When the character set is utf-8, in rare cases it may be desirable to
2005 override the Unicode definition of the type of certain characters.
2011 This can be done by setting the LESSUTFCHARDEF environment variable
2019 If a pair of codepoints is given, the type is set for
2020 all characters inclusively between the two values.
2023 The type character may be one of:
2043 The \-P option allows you to tailor the prompt to your preference.
2044 The string given to the \-P option replaces the specified prompt string.
2045 Certain characters in the string are interpreted specially.
2046 The prompt mechanism is rather complicated to provide flexibility,
2047 but the ordinary user need not understand the details of constructing
2051 according to what the following character is.
2052 (References to the input file size below refer to the preprocessed size,
2055 Replaced by the byte offset into the current input file.
2056 The b is followed by a single character (shown as \fIX\fP above)
2057 which specifies the line whose byte offset is to be used.
2058 If the character is a "t", the byte offset of the top line in the
2060 an "m" means use the middle line,
2061 a "b" means use the bottom line,
2062 a "B" means use the line just after the bottom line,
2063 and a "j" means use the "target" line, as specified by the \-j option.
2065 Replaced by the size of the current input file.
2067 Replaced by the column number of the text appearing in the first
2068 column of the screen.
2070 Replaced by the page number of a line in the input file.
2071 The line to be used is determined by the \fIX\fP, as with the %b option.
2073 Replaced by the number of pages in the input file,
2074 or equivalently, the page number of the last line in the input file.
2076 Replaced by the name of the editor (from the VISUAL environment variable,
2077 or the EDITOR environment variable if VISUAL is not defined).
2078 See the discussion of the LESSEDIT feature below.
2080 Replaced by the name of the current input file.
2082 Replaced by the last component of the name of the current input file.

2106 The line used is determined by the \fIX\fP as with the %b option.
2111 Usually used at the end of the string, but may appear anywhere.
2113 Normally expands to the word "file".
2114 However if viewing files via a tags list using the \-t option,
2115 it expands to the word "tag".
2117 Replaced by the name of the next input file in the list.
2119 If any item is unknown (for example, the file size if input

2125 depending on the following character, a condition is evaluated.
2126 If the condition is true, any characters following the question mark
2127 and condition character, up to a period, are included in the prompt.
2128 If the condition is false, such characters are not included.
2129 A colon appearing between the question mark and the
2131 the colon and the period are included in the string if and only if
2132 the IF condition is false.
2135 True if any characters have been included in the prompt so far.
2137 True if the byte offset of the specified line is known.
2139 True if the size of current input file is known.

2162 of the specified line is known.
2167 (that is, if the current input file is not the last one).
2169 Any characters other than the special ones

2172 Any of the special characters may be included in the prompt literally
2179 This prompt prints the filename, if known;
2180 otherwise the string "Standard input".
2184 This prompt would print the filename, if known.
2185 The filename is followed by the line number, if known,
2186 otherwise the percent if known, otherwise the byte offset if known.
2189 and how the % after the %pt
2194 This prints the filename if this is the first prompt in a file,
2195 followed by the "file N of N" message if there is more
2197 Then, if we are at end-of-file, the string "(END)" is printed
2198 followed by the name of the next file, if there is one.
2200 This is the default prompt.
2201 For reference, here are the defaults for
2202 the other two prompts (\-m and \-M respectively).
2213 And here is the default message produced by the = command:
2220 The prompt expansion features are also used for another purpose:
2222 as the command to be executed when the v command is invoked.
2223 The LESSEDIT string is expanded in the same way as the prompt strings.
2224 The default value for LESSEDIT is:
2230 Note that this expands to the editor name, followed by a + and the
2231 line number, followed by the shell-escaped file name.
2232 If your editor does not accept the "+linenumber" syntax, or has other
2233 differences in invocation syntax, the LESSEDIT variable can be
2237 When the environment variable LESSSECURE is set to 1,

2272 Each feature name is the first word in each line in the above list.
2273 A feature name may be abbreviated as long as the abbreviation is unambiguous.
2282 were set, all of the above features would be disabled 
2283 except for history files and the edit command.
2286 In that case, the LESSSECURE and LESSSECURE_ALLOW variables are ignored.
2289 If the environment variable LESS_IS_MORE is set to 1,
2290 or if the program is invoked via a file link named "more",
2292 behaves (mostly) in conformance with the POSIX 
2297 The \-e option works differently.
2298 If the \-e option is not set,
2300 behaves as if the \-e option were set.
2301 If the \-e option is set,
2303 behaves as if the \-E option were set.
2305 The \-m option works differently.
2306 If the \-m option is not set, the medium prompt is used,
2307 and it is prefixed with the string "\-\-More\-\-".
2308 If the \-m option is set, the short prompt is used.
2310 The \-n option acts like the \-z option.
2311 The normal behavior of the \-n option is unavailable in this mode.
2313 The parameter to the \-p option is taken to be a
