remove a delta from an SCCS file
rmdel -r SID files
The rmdel command 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 delta specified must not be that of
a version being edited for the purpose of making a delta (that is,
if a p-file (see
exists for the
named SCCS file, the delta specified must not
appear in any entry of the p-file).
The -r option is used for specifying the SID
(SCCS identification) 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 and unreadable files are silently ignored.
If a name of ``-'' is given, standard input is read;
each line of the standard input is taken to be the name of an
SCCS file to be processed.
Simply stated, if you make a delta then you can remove it,
or if you own the file and directory then you can remove a delta.
rmdel is conformant with:
