WHAT(1) (Source Code Control System Utilities) WHAT(1)
NAME
what - identify SCCS files
SYNOPSIS
what [-s] files
DESCRIPTION
what searches the given files for all occurrences of the
pattern that get(1) substitutes for %Z% (this is @(#) at
this printing) and prints out what follows until the first
~, >, new-line, \, or null character. For example, if the C
program in file f.c contains
char ident[] = "@(#)identification information";
and f.c is compiled to yield f.o and a.out, then the command
what f.c f.o a.out
will print
f.c:
identification information
f.o:
identification information
a.out:
identification information
what is intended to be used in conjunction with the command
get(1), which automatically inserts identifying information,
but it can also be used where the information is inserted
manually. Only one option exists:
-s Quit after finding the first occurrence of
pattern in each file.
SEE ALSO

DIAGNOSTICS
Exit status is 0 if any matches are found, otherwise 1. Use
help(1) for explanations.
BUGS
It is possible that an unintended occurrence of the pattern
@(#) could be found just by chance, but this causes no harm
in nearly all cases.
