what filename...

The what utility searches each filename for occurrences of the pattern @(#) that the SCCS get command (see get(1)) substitutes for the @(#) ID keyword, and prints what follows up to a ", >, NEWLINE, \, or NULL character. For example, 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:

$ what program.c program.o a.out

produces:

program.c:	identification information
program.o:	identification information
a.out:	identification information

The following option is accepted:

-s	Stops after the first occurrence of the pattern.
The following exit values are returned:
0	Any matches were found.
1	No matches found.

get(1), help(1)

Use the SCCS help command for explanations (see help(1)).

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