.SH DESCRIPTION
.SS "/usr/bin/wc"
.sp
.LP
\fBwc\fR reads one or more input files and, by default, writes the number of
NEWLINE characters, words and bytes contained in each input file to the
standard output.
.sp
.LP
\fBwc\fR also writes a total count for all named files, if more than one input
file is specified.
.sp
.LP
\fBwc\fR considers a \fIword\fR to be a non-zero-length string of characters
delimited by white space (for example, \fBSPACE\fR, \fBTAB\fR). See
\fBiswspace\fR(3C) or \fBisspace\fR(3C).
.SS "ksh93"
.sp
.LP
The \fBwc\fR built-in in \fBksh93\fR is associated with the \fB/bin\fR and
\fB/usr/bin\fR paths. It is invoked when \fBwc\fR is executed without a
pathname prefix and the pathname search finds a \fB/bin/wc\fR or
\fB/usr/bin/wc\fR executable.
.sp
.LP
\fBwc\fR reads one or more input files and, by default, for each file writes a
line containing the number of NEWLINEs, words, and bytes contained in each file
followed by the file name to standard output in that order. A word is defined
to be a \fBnon-zero\fR length string delimited by \fBisspace\fR(3C) characters.
.sp
.LP
If more than one file is specified, \fBwc\fR writes a total count for all of
the named files with total written instead of the file name.
.sp
.LP
By default, \fBwc\fR writes all three counts. Options can specified so that
only certain counts are written. The \fB-c\fR, \fB-C\fR, and \fB-m\fR options
are mutually exclusive.
.sp
.LP
If no file is specified, or if the file is \fB-\fR, \fBwc\fR reads from
standard input and no filename is written to standard output. The start of the
file is defined as the current offset.
