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 inter-
       preted 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  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 .

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 cre-
       ated 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.
