.Sh NAME
.Nm what
.Nd "show what versions of object modules were used to construct a file"
.Sh SYNOPSIS
.Nm
.Op Fl qs
.Op Ar
.Sh DESCRIPTION
The
.Nm
utility searches each specified
.Ar file
for sequences of the form
.Dq Li @(#)
as inserted by the
.Tn SCCS
source code control system.
It prints the remainder
of the string following this marker, up to a NUL character, newline, double
quote,
.Ql \&>
character, or backslash.
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl q
Only output the match text, rather than formatting it.
.It Fl s
Stop searching each file after the first match.
.El
.Sh EXIT STATUS
Exit status is 0 if any matches were found, otherwise 1.
.Sh SEE ALSO
.Xr ident 1 ,
.Xr strings 1
.Sh STANDARDS
The
.Nm
utility conforms to
.St -p1003.1-2001 .
The
.Fl q
option is a non-standard
.Fx
extension which may not be available on other operating systems.
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.0 .
.Sh BUGS
This is a rewrite of the
.Tn SCCS
command of the same name,
and behavior may not be identical.
