.Sh DESCRIPTION
|
|
The
|
|
.Nm wc
|
|
utility reads one or more input text files, and, by
|
|
default, writes the number of lines, words, and bytes
|
|
contained in each input file to the standard output.
|
|
If more than one input file is specified,
|
|
a line of cumulative count(s) for all named files is output on a
|
|
separate line
|
|
following the last file count.
|
|
.Nm Wc
|
|
considers a word to be a maximal string of
|
|
characters delimited by white space.
|
|
.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 wc
|
|
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

|
A pathname of an input file.
|
|
.El
|
|
.Pp
|
|
If no file names
|
|
are specified, the standard input is used and
|
|
a file name is not output. The resulting output is one
|
|
line of the requested count(s) with the cumulative sum
|
|
of all files read in via standard input.
|
|
.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
|
|
The counts for lines, words and bytes are integers separated
|
|
by spaces.
|
|
.Pp
|
|
The
|
|
.Nm wc
|
|
utility exits 0 on success, and >0 if an error occurs.

|
|
.Nm wc
|
|
utility conforms to
