The 84default action is equivalent to all the 85flags 86.Fl clw 87having been specified. 88.Pp 89The following operands are available: 90.Bl -tag -width Ds 91.It Ar file 92A pathname of an input file. 93.El 94.Pp 95If no file names 96are specified, the standard input is used and 97a file name is not output. The resulting output is one 98line of the requested count(s) with the cumulative sum 99of all files read in via standard input. 100.Pp 101By default, the standard output contains a line for each 102input file of the form: 103.Bd -literal -offset indent 104lines words bytes file_name 105.Ed 106.Pp 107The counts for lines, words and bytes are integers separated 108by spaces. 109.Pp 110The 111.Nm wc 112utility exits 0 on success, and >0 if an error occurs. 113.Sh STANDARDS 114The 115.Nm wc 116utility conforms to 117.St -p1003.2-92 . 118
