NAME

  unget	- Cancels a previous get command

SYNOPSIS

  unget	[-n] [-s] [-r SID] file... | -

STANDARDS

  Interfaces documented	on this	reference page conform to industry standards
  as follows:

  unget:  XCU5.0

  Refer	to the standards(5) reference page for more information	about indus-
  try standards	and associated tags.

OPTIONS

  Each option or group of options applies independently	to each	named file.

  -n  Prevents the automatic deletion of the file obtained by get, the g-
      file.  This option lets you retain the edited version of the file
      without making a delta.

  -r SID
      Specifies	the new	delta that would have been created by the next use of
      the delta	command.  You must use this option if you have two or more
      pending deltas to	the file under the same	login name.  You can look at
      the p-file to see	if you have more than one delta	pending	to a particu-
      lar SID under the	same login name.  The SID specification	must unambi-
      guously specify only one SID to discard, or unget	displays an error
      message and stops	running.

  -s  Suppresses displaying the	deleted	SID.

OPERANDS

  file
      Pathname of an existing SCCS file	or directory.  If you specify a
      directory	unget performs the requested actions on	all SCCS files (those
      files with the s.	prefix).

      If you specify a - (dash)	in place of file, standard input is read, and
      each line	of standard input is interpreted as the	name of	a Source Code
      Control System (SCCS) file.  An End-of-File character terminates input.







DESCRIPTION

  The unget command lets you restore a g-file created with a get -e before
  the new delta	is created, and	therefore discard the changes (see the get
  and delta commands).

  The unget command lets you reverse the effect	of a get -e command done
  prior	to creating the	intended new delta.

  [Tru64 UNIX]	The file name or names refer to	the SCCS s-files, not the g-
  files.  If the s-files are not in the	working	directory, the names must
  include the path to the SCCS directory.

  During processing of file, a locking z-file, and a q-file (a working copy
  of the p-file), may be created and deleted. The p-file and g-file are
  deleted.  See	get(1) for the descriptions and	usage of these files.

EXIT STATUS

  The following	exit values are	returned.

  0   Successful completion.

  >>0  An error occurred.

EXAMPLES

   1.  To discard the changes you have made to an SCCS file after doing	a get
       -e, enter:
	    unget s.prog.c

   2.  The previous example illustrates	use of unget for an s-file in the
       working directory.  The following example illustrates use of the	com-
       mand for	an s-file in a different directory:
	    unget /usr/projects/myproject/SCCS/s.prog.c



ENVIRONMENT VARIABLES

  The following	environment variables affect the execution of unget:

  LANG
      Provides a default value for the internationalization variables that
      are unset	or null. If LANG is unset or null, the corresponding value
      from the implementation-specific default locale is used. If any of the
      internationalization variables contain an	invalid	setting, unget
      behaves as if none of the	variables had been defined.

  LC_ALL
      If set to	a non-empty string value, overrides the	values of all the
      other internationalization variables.

  LC_TYPE
      Determines the locale for	the interpretation of sequences	of bytes of
      text data	as characters (for example, single, as opposed to multibyte,
      characters in arguments and input	files).

  LC_MESSAGES
      Determines the locale that should	be used	to affect the format and con-
      tents of diagnostic messages written to standard error.

  NLSPATH
      Determines the location of message catalogues for	the processing of
      LC_MESSAGES.
