rmdel(1)          (Source Code Control System Utilities)           rmdel(1)


   NAME
         rmdel - remove a delta from an SCCS file

   SYNOPSIS
         rmdel -rSID files

   DESCRIPTION
         rmdel removes the delta specified by the SID (SCCS identification
         string) 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 delta specified must not be
         that of a version being edited for the purpose of making a delta;
         that is, if a p-file exists for the named SCCS file [see get(1)], the
         delta specified must not appear in any entry of the p-file.

         The -r option specifies the SID 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.

         The rules governing the removal of a delta are as follows:  if you
         make a delta and have appropriate file permissions, you can remove
         it; if you own the file and directory in which a new delta file
         resides, you can remove the delta.

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

   EXAMPLE
         The following example removes the latest version (i.e. 1.2) for
         s.test1.c.

               rmdel -r1.2 s.test1.c
