MirBSD manpage: what(1)
WHAT(1) BSD 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 the form "@(#)" as in-
serted 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
("POSIX.1") specification. In MirBSD #5 and up, the ability to operate on
standard input is restored.
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.
