A line is defined as a string of characters delimited by a <newline> character, and a word is defined as a string of characters delimited by white space characters. White space characters are the set of characters for which the .Xr isspace 3 function returns true. If more than one input file is specified, a line of cumulative counts for all the files is displayed on a separate line after the output for the last file. .Pp The following options are available: .Bl -tag -width Ds .It Fl c The number of bytes in each input file is written to the standard output. .It Fl l The number of lines in each input file is written to the standard output. .It Fl m The number of characters in each input file is written to the standard output. .It Fl w The number of words in each input file is written to the standard output. .El .Pp When an option is specified, .Nm only reports the information requested by that option. The default action is equivalent to all the flags .Fl clw having been specified. .Pp The following operands are available: .Bl -tag -width Ds .It Ar file A pathname of an input file. .El .Pp If no file names are specified, the standard input is used and no file name is displayed. .Pp By default, the standard output contains a line for each input file of the form: .Bd -literal -offset indent lines words bytes file_name .Ed .Pp .Pp The .Nm utility exits 0 on success, and >0 if an error occurs. .Sh SEE ALSO .Xr isspace 3 .Sh COMPATIBILITY Historically, the .Nm utility was documented to define a word as a ``maximal string of characters delimited by <space>, <tab> or <newline> characters''. The implementation, however, didn't handle non-printing characters correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar'' counted as 8 characters. .Bx 4 systems after .Bx 4.3 modified the implementation to be consistent with the documentation. This implementation defines a ``word'' in terms of the .Xr isspace 3 function, as required by .St -p1003.2 . .Sh STANDARDS The .Nm utility conforms to .St -p1003.2-92 .
