The 80default action is equivalent to all the 81flags 82.Fl clw 83having been specified. 84.Pp 85The following operands are available: 86.Bl -tag -width Ds 87.It Ar file 88A pathname of an input file. 89.El 90.Pp 91If no file names 92are specified, the standard input is used and 93a file name is not output. The resulting output is one 94line of the requested count(s) with the cumulative sum 95of all files read in via standard input. 96.Pp 97By default, the standard output contains a line for each 98input file of the form: 99.Bd -literal -offset indent 100lines words bytes file_name 101.Ed 102.Pp 103The counts for lines, words and bytes are integers separated 104by spaces. 105The ordering of the display of the number of lines, words, 106and/or bytes is the order in which the options were specified. 107.Pp 108The 109.Nm wc 110utility exits 0 on success, and >0 if an error occurs. 111.Sh STANDARDS 112The 113.Nm wc 114function conforms to 115.St -p1003.2 . 116
