+.Os
+.Sh NAME
+.Nm what
+.Nd show what versions of object modules were used to construct a file
+.Sh SYNOPSIS
+.Nm what
+.Op Fl s
+.Ar
+.Sh DESCRIPTION
+.Nm
+reads each
+.Ar file
+and searches for sequences of either the form
+.Sq $
+immediately followed by the system name (sysname) as defined by
+.Xr uname 3 ,
+or the form
+.Dq @(#)
+as inserted by the source code control system (SCCS).
+.Pp
+When
+.Sq $
+followed by the system name is encountered
+.Nm
+prints the remainder of the string up to a
+.Sq $
+or any non-printable character.
+.Pp
+When
+.Dq @(#)
+is encountered
+.Nm
+prints the remainder of the string, up to a NUL, newline, double
+quote, backslash, or
+.Sq >
+character.
+.Pp
+If the
+.Fl s
+option is specified, only the first occurrence of an identification string in
+each file is printed.
+.Sh EXIT STATUS
+The
+.Nm
+utility exits with a return value of 0 if any identification strings were found,
+or with a return value of 1 otherwise.
+.Sh STANDARDS
+The
+.Nm
+utility is compliant with the
+X/Open System Interfaces option of the
+.St -p1003.1-2008
+specification.
+.Pp
+Processing $sysname$ sequences is an
+.Ox
+extension.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.0 .
+.Sh BUGS
+As
+.Bx
+is not licensed to distribute
+.Tn SCCS ,
+this is a rewrite of the
+.Nm
+command which is part of
+.Tn SCCS .
+As such it may not behave exactly the same as that
+command does.
