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

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

NAME
       unget - undo a previous get of an SCCS file (DEVELOPMENT)

SYNOPSIS
       unget [-ns][-r SID] file...

DESCRIPTION
       The unget utility shall reverse the effect of a get -e done prior to creating the intended
       new delta.

OPTIONS
       The unget utility shall conform to the Base Definitions	volume	of  IEEE Std 1003.1-2001,
       Section 12.2, Utility Syntax Guidelines.

       The following options shall be supported:

       -r  SID
	      Uniquely	identify  which delta is no longer intended. (This would have been speci-
	      fied by get as the new delta.) The use of this option is necessary only if  two  or
	      more  outstanding  get  commands for editing on the same SCCS file were done by the
	      same person (login name).

       -s     Suppress the writing to standard output of the intended delta's SID.

       -n     Retain the file that was obtained by get, which would normally be removed from  the
	      current directory.

OPERANDS
       The following operands shall be supported:

       file   A  pathname  of  an  existing SCCS file or a directory. If file is a directory, the
	      unget 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 shall be taken to be the name of an SCCS file to be pro-
       cessed.	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
       Any SCCS files processed shall be files of an unspecified format.

ENVIRONMENT VARIABLES
       The following environment variables shall affect the execution of unget:

       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
       The standard output shall consist of a line for each file, in the following format:

	      "%s\n", <SID removed from file>

       If there is more than one named file or if a directory or standard input  is  named,  each
       pathname shall be written before each of the preceding lines:

	      "\n%s:\n", <pathname>

STDERR
       The standard error shall be used only for diagnostic messages.

OUTPUT FILES
       Any  SCCS  files  updated  shall be files of an unspecified format. During processing of a
       file, a locking z-file, as described in get, and a q-file (a working copy of the  p-file),
       may be created and deleted. The p-file and g-file, as described in get, shall be deleted.

EXTENDED DESCRIPTION
       None.

EXIT STATUS
       The following exit values shall be returned:

	0     Successful completion.

       >0     An error occurred.

CONSEQUENCES OF ERRORS
       Default.
