+.Nd word, line, and byte count
+.Sh SYNOPSIS
+.Nm wc
+.Op Fl clw
+.Op Ar file ...
+.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 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
+.It Ar file
+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.
+The ordering of the display of the number of lines, words,
+and/or bytes is the order in which the options were specified.
+.Pp
+The
+.Nm wc
+utility exits 0 on success, and >0 if an error occurs.
+.Sh STANDARDS
+The
+.Nm wc
+function conforms to
+.St -p1003.2 .
