NAME
what - extract SCCS version information from a file

SYNOPSIS

what
[-s]
filename...

DESCRIPTION

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.

OPTIONS

The following option is supported:

-s  Stops after the first occurrence of the pattern.

-V  Prints the what version number string and exists.

EXAMPLES

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

EXIT STATUS

The following exit values are returned:

0   Any matches were found.

1   No matches found.
