+.Sh NAME
+.Nm wc
+.Nd word, line, and byte count
+.Sh SYNOPSIS
+.Nm
+.Op Fl c | Fl m
+.Op Fl Llw
+.Op Ar file ...
+.Sh DESCRIPTION
+The
+.Nm
+utility displays the number of lines, words, bytes and characters contained in each
+input
+.Ar file
+(or standard input, by default) to the standard output.
+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 iswspace 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 characters in the longest line of 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
+.Sh EXIT STATUS
+.Ex -std wc
+.Sh COMPATIBILITY
+Historically, the
+.Nm
+utility was documented to define a word as a ``maximal string of
+characters delimited by
+.Aq space ,
+.Aq tab
+or
+.Aq 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 iswspace 3
+function, as required by
+.St -p1003.2 .
+.Pp
+The
+.Fl L
+option is a non-standard extension, compatible with the
+.Fl L
+option of the GNU and
+.Fx
+.Nm
+utilities.
+.Sh SEE ALSO
+.Xr iswspace 3
+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.2-92 .
