NAME

what − extract SCCS version information from a file

SYNOPSIS

what [ −s ] filename ...

DESCRIPTION

what 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.  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

produces:

program.c:
identification information

program.o:
identification information

a.out:
identification information

OPTIONS

−s Stop after the first occurrence of the pattern.

BUGS

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