Linux 2.6 - man page for rmdel (linux section 1posix)

RMDEL(P)			    POSIX Programmer's Manual				 RMDEL(P)

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, Inter-
	      nationalization 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  interna-
	      tionalization 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  argu-
	      ments and input files).

       LC_MESSAGES
	      Determine the locale that should be used to affect the format and contents of diag-
	      nostic 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 tempo-
       rary  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.
