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

SYNOPSIS
       rmdel -r SID file...

DESCRIPTION
       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

OPTIONS
       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.

OPERANDS
       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.

STDIN
       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.

INPUT FILES
       The SCCS files shall be files of unspecified format.

ENVIRONMENT VARIABLES
       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 Vari-
              ables 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 .

ASYNCHRONOUS EVENTS
       Default.

STDOUT
       Not used.

STDERR
       The standard error shall be used only for diagnostic messages.

OUTPUT FILES
       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.

EXTENDED DESCRIPTION
       None.

EXIT STATUS
       The following exit values shall be returned:

        0     Successful completion.

       >0     An error occurred.

CONSEQUENCES OF ERRORS
       Default.

       The following sections are informative.

APPLICATION USAGE
       None.

EXAMPLES
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
       None.
