NAME    [Toc]    [Back]

     what - identify SCCS files

SYNOPSIS    [Toc]    [Back]

     what [-s] files

DESCRIPTION    [Toc]    [Back]

     what searches the given files for all occurrences of the pattern that
     get(1) substitutes	for %Z%	(this is @(#) at this printing)	and prints out
     what follows until	the first ~, >,	new-line, \, or	null character.	 For
     example, if the C program in file f.c contains

	  char ident[] = "@(#)identification information";

     and f.c is	compiled to yield f.o and a.out, then the command

	  what f.c f.o a.out

     will print

	  f.c:
		  identification information

	  f.o:
		  identification information

	  a.out:
		  identification information

     what is intended to be used in conjunction	with the  command get(1),
     which automatically inserts identifying information, but it can also be
     used where	the information	is inserted manually.  Only one	option exists:

	  -s	  Quit after finding the first occurrence of pattern in	each
		  file.

DIAGNOSTICS    [Toc]    [Back]

     Exit status is 0 if any matches are found,	otherwise 1.  Use help(1) for
     explanations.

BUGS    [Toc]    [Back]

     It	is possible that an unintended occurrence of the pattern @(#) could be
     found just	by chance, but this causes no harm in nearly all cases.
