RMDEL(1P) POSIX Programmer's Manual RMDEL(1P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
rmdel — remove a delta from an SCCS file (DEVELOPMENT)
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(1p)) 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
POSIX.1‐2008, 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 POSIX.1‐2008, 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(1p),
may be created and deleted; a locking z-file, as described in
get(1p), may be created and deleted.
None.
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Default.
The following sections are informative.
None.
None.
None.
None.
