NAME

what - extract version information from a file

SYNOPSIS

what [ -s ] filename ...

DESCRIPTION

what searches each filename for occurrences of the pattern @(#) that the SCCS get command substitutes for the %Z% ID keyword, and prints what follows up to a ", >, NEWLINE, \, or null character. What can be used on any type of file, NOT just SCCS files. Just put the magic 4 character @(#) pattern in your file and you are set.

OPTIONS

-s Stop after the first occurrence of the pattern.

ENVIRONMENT

The working of what is not influenced by any environment variables.

EXAMPLES

If a Perl program test1.pl contains:

  my $REV = '@(# ) $Revision: 1.3 ...

and a C program test2.c contains:

  char rcsid[] = "@(# ) $Revision: 1.15 ....

and the C program is compiled to a.out...

The command:

prompt%> what test1.pl test2.c a.out

produces:

test1.pl: $Revision: 1.3 $';

test2.c: $Revision: 1.15 $";

a.out; $Revision: 1.15 $

BUGS

what has no known bugs.
