WHAT(1) OpenBSD Reference Manual WHAT(1)
what - show what versions of object modules were used to construct a file
what [-s] file [...]
what reads each file and searches for sequences of either the form ``$''
immediately followed by the system name (sysname) as defined by uname(3),
or the form ``@(#)'' as inserted by the source code control system. It
prints the remainder of the string following this marker, up to a NUL,
newline, double quote, backslash, or `>' character.
If the -s option is specified, only the first occurrence of an identifi-
cation string in each file is printed.
The what utility exits with a return value of 0 if any identification
strings were found, or with a return value of 1 otherwise.
The what utility is expected to be a superset of the IEEE Std 1003.1
The what command appeared in 4.0BSD.
As BSD is not licensed to distribute SCCS, this is a rewrite of the what
command which is part of SCCS. As such it may not behave exactly the
same as that command does.
