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 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 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.
