NAME¶
sccs-rmdel, rmdel - remove a delta from an SCCS file
SYNOPSIS¶
/usr/ccs/bin/rmdel [-d] -rsid [-q [nsedelim]] [-z]
[-X extended-options] [-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 one 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:
- ++
- If bulk-spec is preceded by a `++', rmdel(1) expects
to process filenames that are prepended by a plus sign, the related
SID and another plus sign following the form:
+sid+filename
This permits each file to be retrieved with an individual SID.
- space
- This is a placeholder dummy flag that allows one to use a prepared string for the -N option and to replace the space character by one of the supported flags on demand.
The following path specifier types are supported:
- -N
- The file name parameters to the rmdel command are not s.filename files but the names of the g-files. The s.filename names are automatically derived from the g-file names by prepending s. to the last path name component. Both, s.filename and the g-file are in the same directory.
- -Ns.
- The file name parameters to the rmdel command are s.filename files. The the g-files names are automatically derived by removing s. from the beginning of last path name component of the s.filename. Both, s.filename and the g-file are in the same directory.
- -Ndir
- The file name parameters to the rmdel command are not s.filename files but the names of the g-files. The s.filename names are put into directory dir, the names are automatically derived from the g-file names by prepending dir/s. to the last path name component.
- -Ndir/s.
- The file name parameters to the rmdel command are s.filename files in directory dir. The the g-files names are automatically derived by removing dir/s. from the beginning of last path name component of the s.filename.
A typical value for dir is SCCS.
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.
- -Xextended-options
- Specify extended options. The argument extended-options may be a
comma separated list of extended option names.
The following extended options are supported, they may be abbreviated as long ad the abbreviation is still unique. Options with parameter may not be abbreviated.
- 0
- When reading filenames from stdin, triggered by a file name argument `-', the filename separator is a null byte instead of a newline. This allows one to use long lists with arbitrary filenames.
- help
- Print a short online help for available options.
The -X option is a SCHILY extension that does not exist in historic sccs implementations.
ENVIRONMENT VARIABLES¶
See environ(7) 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(5).
- 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(7) for descriptions of the following attributes:
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
| Availability | SUNWsprot |
| Interface Stability | Standard |
