NAME
sccs-rmdel, rmdel - remove a delta from an SCCS file
SYNOPSIS
/usr/ccs/bin/rmdel [-d] -rsid [-q [nsedelim]] [-z]
[-N bulk-spec] s.filename...
DESCRIPTION
The rmdel utility removes the delta specified by the SCCS delta ID (SID) supplied with -r. The delta to be removed must be the most recent (leaf) delta in its branch. In addition, the SID must not be that of a version checked out for editing: it must not appear in any entry of the version lock file (p.file).
If you created the delta, or, if you own the file and directory and have write permission, you can remove it with rmdel.
If a directory name is used in place of the s.filename argument, the rmdel command applies to all s.files in that directory. Unreadable s.files produce an error; processing continues with the next file (if any). The use of ‘-’ as the s.filename argument indicates that the names of files are to be read from the standard input, one s.file per line.
OPTIONS
The following option is supported:
-d | Fully discard the delta. By default only the file content for the related SID is removed and the delta table entry is changed to the new type ‘R’. When in discard mode, the delta table entry is also completely discarded. | ||||||||||||||
-rsid | Remove the version corresponding to the indicated SID (delta). This option is mandatory. | ||||||||||||||
-q[nsedelim] | |||||||||||||||
Enable NSE mode. If NSE mode is enabled, several NSE related extensions may be used. In this release, the value of nsedelim is ignored.
This option is an undocumented SUN extension that does not exist in historic sccs implementations.
|
|||||||||||||||
-z | Enable CMF extensions for MR number handling.
This option is an undocumented SUN extension that does not exist in historic sccs implementations.
|
||||||||||||||
-Nbulk-spec | |||||||||||||||
Processes a bulk of SCCS history files. This option allows to do an efficient mass processing of SCCS history files.
The bulk-spec parameter is composed from an optional list of flag parameters followed by an optional path specifier.
The following flag types are supported:
In order to overcome the limited number of exec(2) arguments, it is recommended to use ‘-’ as the file name parameter for rmdel(1) and to send a list of path names to stdin.
This option is a SCHILY extension that does not exist in historic sccs implementations.
|
|||||||||||||||
-V
-version --version |
Prints the rmdel version number string and exists.
This option is a SCHILY extension that does not exist in historic sccs implementations.

ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of rmdel(1): LANG, LC_ALL, LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH.
SCCS_NO_HELP | |
If set, rmdel(1) will not automatically call help(1) with the SCCS error code in order to print a more helpful error message. Scripts that depend on the exact error messages of SCCS commands should set the environment variable SCCS_NO_HELP and set LC_ALL=C. |
EXIT STATUS
The following exit values are returned:
0 | Successful completion. |
1 | An error occurred. |
FILES
p.file | permissions (lock) file for checked-out versions. See sccs-get(1) for a description of the layout of the p.file. |
s.file | SCCS history file, see sccsfile(4). |
x.file | temporary copy of the s.file; renamed to the s.file after completion |
z.file | temporary lock file contains the binary process id in host byte order followed by the host name |
dump.core | If the file dump.core exists in the current directory and a fatal signal is received, a coredump is initiated via abort(3). |
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
ATTRIBUTE TYPE | ATTRIBUTE VALUE |

AUTHORS
The SCCS suite was originally written by Marc J. Rochkind at Bell Labs in 1972. Release 4.0 of SCCS, introducing new versions of the programs admin(1), get(1), prt(1), and delta(1) was published on February 18, 1977; it introduced the new text based SCCS v4 history file format (previous SCCS releases used a binary history file format). The SCCS suite was later maintained by various people at AT&T and Sun Microsystems. Since 2006, the SCCS suite is maintained by J..org Schilling.
