WHAT(1) BSD Reference Manual WHAT(1)
what - show what versions of object modules were used to construct a file
what name ...
What reads each file name and searches for sequences of 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.''
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.
The what command appeared in 4.0BSD.
