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

SYNOPSIS
     what name [...]

DESCRIPTION
     what reads each file name 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 null character, newline, double quote, or `>' character.

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, and may not behave exactly the same as
     that command does.
