The what utility searches each filename for occurrences of the pattern @(#) that the SCCS get command (see sccs-get(1)) substitutes for the %Z% ID keyword, and prints what follows up to a ", >, NEWLINE, \, or NULL character.
The following option is supported:
-s Stops after the first occurrence of the pattern.
Example 1: Extracting SCCS version information
If a 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:
example% what program.c program.o a.out
produces:
program.c: identification information
program.o: identification information
a.out: identification information
The following exit values are returned:
0 Any matches were found.
1 No matches found.
See environ(5) for descriptions of the following environment variables that affect the execution of what: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.
See attributes(5) for descriptions of the following attributes:

There is a remote possibility that a spurious occurrence of the `@(#)' pattern could be found by what.
