Name

what - extract SCCS version information from a file

Synopsis

what [ -s ] filename ...

Availability

SUNWsprot

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.

Options

-s
Stop after the first occurrence of the pattern.

Examples

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:

example% what program.c program.o a.out

produces:

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

Bugs

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