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.
