show what versions of object modules were used to construct a file
NAME
what – show what versions of object modules were used to construct a file
SYNOPSIS
what [-qs] [file ...]
DESCRIPTION
The what utility searches each specified file for sequences of the form “@(#)” as inserted by the SCCS source code control system. It prints the remainder of the string following this marker, up to a NUL character, newline, double quote, ‘>’ character, or backslash.
The following options are available:
-q
Only output the match text, rather than formatting it.
-s
Stop searching each file after the first match.
EXIT STATUS
Exit status is 0 if any matches were found, otherwise 1.
The what utility conforms to IEEE Std 1003.1-2001 (“POSIX.1”). The -q option is a non-standard FreeBSD extension which may not be available on other operating systems.
HISTORY
The what command appeared in 4.0BSD.
BUGS
This is a rewrite of the SCCS command of the same name, and behavior may not be identical.
