Source Code Control System

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
-version
--version
Prints the what version number string and exists.
This option is a SCHILY extension that does not exist in historic sccs implementations.

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

ENVIRONMENT VARIABLES

See environ(5) for descriptions of the following environment variables that affect the execution of what: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.

AUTHORS

The SCCS suite was originally written by Marc J. Rochkind at Bell Labs in 1972. Release 4.0 of SCCS, introducing new versions of the programs admin(1), get(1), prt(1), and delta(1) was published on February 18, 1977; it introduced the new text based SCCS v4 history file format (previous SCCS releases used a binary history file format). The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite is maintained by J..org Schilling.
