WHAT(1) General Commands Manual WHAT(1)
what - extract SCCS version information from a file
what [ -s ] filename ...
what searches each filename for occurrences of the pattern @(#) that
the SCCS get command (see sccs-get(1)) substitutes for the %Z% ID key-
word, and prints what follows up to a ", >>, NEWLINE, \, or null charac-
ter. For instance, if the C program in file program.c contains
char sccsid = "@(#)identification information";
and program.c is compiled to yield program.o and a.out, the command:
what program.c program.o a.out
a.out: identification information
-s Stop after the first occurrence of the pattern.

Use the SCCS help command for explanations (see sccs-help(1)).
There is a remote possibility that a spurious occurrence of the `@(#)'
pattern could be found by what.
