MirOS Manual: what(1)

WHAT(1)                      BSD Reference Manual                      WHAT(1)

NAME

     what - show what versions of object modules were used to construct a file

SYNOPSIS

     what [-s] [file [...]]

DESCRIPTION

     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.

EXIT STATUS

     The what utility exits with a return value of 0 if any identification
     strings were found, or with a return value of 1 otherwise.

STANDARDS

     The what utility is expected to be a superset of the IEEE Std 1003.1
     ("POSIX") specification. In MirOS #5 and up, the ability to operate on
     standard input is restored.

HISTORY

     The what command appeared in 4.0BSD.

BUGS

     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.
