NAME

rmdel - remove a delta from an SCCS file (DEVELOPMENT)

 SYNOPSIS

rmdel -r SID file...

 DESCRIPTION

The rmdel utility removes the delta specified by the SID from each named SCCS file. The delta to be removed must be the 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; that is, if a p@file (see get) exists for the named SCCS file, the SID specified must not appear in any entry of the p@file.

Removal of a delta is 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.

 OPTIONS

The rmdel utility supports the XBD specification, Utility Syntax Guidelines  . The following option is supported:

-r SID

Specify the SCCS identification string ( SID ) of the delta to be deleted.

 OPERANDS

The following operands are supported:

file

A pathname of an existing SCCS file or a directory. If file is a directory, rmdel behaves 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 are silently ignored. If a single instance file is specified as -, 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.

 STDIN

The standard input is a text file used only when the file operand is specified as -. Each line of the text file is interpreted as an SCCS pathname.

 INPUT FILES

The SCCS files are files of unspecified format.

 ENVIRONMENT VARIABLES

The following environment variables affect the execution of rmdel:

LANG

Provide a default value for the internationalisation variables that are unset or null. If LANG is unset or null, the corresponding value from the implementation-dependent default locale will be used. If any of the internationalisation variables contains an invalid setting, the utility will behave as if none of the variables had been defined.

LC_ALL

If set to a non-empty string value, override the values of all the other internationalisation variables.

LC_CTYPE

Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single- 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 catalogues for the processing of LC_MESSAGES .

 ASYNCHRONOUS EVENTS

Default.

 STDOUT

Not used.

 STDERR

Used only for diagnostic messages.

 OUTPUT FILES

The SCCS files are 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.

 EXTENDED DESCRIPTION

0

Successful completion.

>0

An error occurred.

 CONSEQUENCES OF ERRORS
