NAME
     rmdel - remove a delta from an SCCS file

SYNOPSIS
     rmdel -rSID files

DESCRIPTION
     rmdel removes the delta specified by the SID from each named
     SCCS file.  The delta to be removed must be the newest (most
     recent) delta in its branch in the delta chain of each named
     SCCS file.  In addition, the  specified must not be that of
     a version being edited for the purpose of making a delta (i.
     e., if a p-file [see get(1)] exists for the named SCCS file,
     the  specified must not appear in any entry of the p-file).

     The -r option is used for specifying the SID (SCCS IDentifi-
     cation) level of the delta to be removed.

     If a directory is named, rmdel behaves as though each file
     in the directory were specified as a named file, except that
     non-SCCS files (last component of the path name does not
     begin with s.)  and unreadable files are silently ignored.
     If a name of - is given, the standard input is read; each
     line of the standard input is taken to be the name of an
     SCCS file to be processed; non-SCCS files and unreadable
     files are silently ignored.

     Simply stated, they are either (1) if you make a delta you
     can remove it; or (2) if you own the file and directory you
     can remove a delta.

FILES
     x.file    [see delta(1)]
     z.file    [see delta(1)]
