NAME
     wc	-- word, line, character, and byte count

SYNOPSIS
     wc	[-clmw]	[file ...]

DESCRIPTION
     The wc utility displays the number	of lines, words, and bytes contained
     in	each input file	(or standard input, by default)	to the standard	out-
     put.  A line is defined as	a string of characters delimited by a <new-
     line> character, and a word is defined as a string	of characters delim-
     ited by white space characters.  White space characters are the set of
     characters	for which the 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.

     The following options are available:

     -c	     The number	of bytes in each input file is written to the standard
	     output.

     -l	     The number	of lines in each input file is written to the standard
	     output.

     -m	     The number	of characters in each input file is written to the
	     standard output.  If the current locale does not support multi-
	     byte characters, this is equivalent to the	-c option.

     -w	     The number	of words in each input file is written to the standard
	     output.

     When an option is specified, wc only reports the information requested by
     that option.  The default action is equivalent to specifying the -c, -l
     and -w options.

     If	no files are specified,	the standard input is used and no file name is
     displayed.

ENVIRONMENT
     The LANG, LC_ALL and LC_CTYPE environment variables affect	the execution
     of	wc as described	in environ(7).

EXAMPLES
     Count the number of characters, words and lines in	each of	the files
     report1 and report2 as well as the	totals for both:

	   wc -mlw report1 report2

DIAGNOSTICS
     The wc utility exits 0 on success,	and >0 if an error occurs.

SEE ALSO
     iswspace(3)

COMPATIBILITY
     Historically, the wc utility was documented to define a word as a ``maxi-
     mal string	of characters delimited	by <space>, <tab> or <newline> charac-
     ters''.  The implementation, however, didn't handle non-printing charac-
     ters correctly so that ``	^D^E  '' counted as 6 spaces, while
     ``foo^D^Ebar'' counted as 8 characters.  4BSD systems after 4.3BSD	modi-
     fied the implementation to	be consistent with the documentation.  This
     implementation defines a ``word'' in terms	of the iswspace(3) function,
     as	required by IEEE Std 1003.2 (``POSIX.2'').

STANDARDS
     The wc utility conforms to	IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY
     A wc command appeared in Version 1	AT&T UNIX.
