NAME
     what - identify SCCS files

SYNOPSIS
     what [-s] files

DESCRIPTION
     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 ~, >, newline, \, 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

     get(1), which automatically inserts identifying information, can also be
     used where the information is inserted manually.

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

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

BUGS
     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.
