rmdel - remove a delta from an SCCS file (
DEVELOPMENT)
Návod, kniha: POSIX Programmer's Manual
rmdel -r SID file...
The
rmdel utility shall remove the delta specified by the SID from each
named SCCS file. The delta to be removed shall be the most recent delta in its
branch in the delta chain of each named SCCS file. In addition, the
application shall ensure that the SID specified is not that of a version being
edited for the purpose of making a delta; that is, if a
p-file (see
get ) exists for the named SCCS file, the SID specified shall not
appear in any entry of the
p-file.
Removal of a delta shall be restricted to:
- 1.
- The user who made the delta
- 2.
- The owner of the SCCS file
- 3.
- The owner of the directory containing the SCCS file
The
rmdel utility shall conform to the Base Definitions volume of
IEEE Std 1003.1-2001, Section 12.2, Utility Syntax Guidelines.
The following option shall be supported:
- -r SID
- Specify the SCCS identification string ( SID) of the
delta to be deleted.
The following operand shall be supported:
- file
- A pathname of an existing SCCS file or a directory. If
file is a directory, the rmdel utility shall behave as
though each file in the directory were specified as a named file, except
that non-SCCS files (last component of the pathname does not begin with
s.) and unreadable files shall be silently ignored.
If exactly one
file operand appears, and it is
'-' , the standard
input shall be 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 shall be
silently ignored.
The standard input shall be a text file used only when the
file operand
is specified as
'-' . Each line of the text file shall be interpreted
as an SCCS pathname.
The SCCS files shall be files of unspecified format.
The following environment variables shall affect the execution of
rmdel:
- LANG
- Provide a default value for the internationalization
variables that are unset or null. (See the Base Definitions volume of
IEEE Std 1003.1-2001, Section 8.2, Internationalization
Variables for the precedence of internationalization variables used to
determine the values of locale categories.)
- LC_ALL
- If set to a non-empty string value, override the values of
all the other internationalization variables.
- LC_CTYPE
- Determine the locale for the interpretation of sequences of
bytes of text data as characters (for example, single-byte as opposed to
multi-byte characters in arguments and input files).
- LC_MESSAGES
- Determine the locale that should be used to affect the
format and contents of diagnostic messages written to standard error.
- NLSPATH
- Determine the location of message catalogs for the
processing of LC_MESSAGES .
Default.
Not used.
The standard error shall be used only for diagnostic messages.
The SCCS files shall be files of unspecified format. During processing of a
file, a temporary
x-file, as described in
admin , may be
created and deleted; a locking
z-file, as described in
get , may
be created and deleted.
None.
The following exit values shall be returned:
- 0
- Successful completion.
- >0
- An error occurred.
Default.
