NAME

rmdel − remove a delta from an SCCS file

SYNOPSIS

rmdel -r SID file ...

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 SID 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 SID specified must not appear in any entry of the p-file).

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 exact permissions necessary to remove a delta are documented in the Source Code Control System User’s Guide. 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.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the local language equivalent of the affirmative string ("yes").  LANG also determines the language in which messages are displayed. 

If LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. 

If any internationalization variable contains an invalid setting, rmdel behaves as if all internationalization variables are set to "C".  See environ(5).
