unget(1)
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
industry 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
particular SID under the same login name. The SID specification must
unambiguously 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
command 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
contents of diagnostic messages written to standard error.
NLSPATH
Determines the location of message catalogues for the processing of
LC_MESSAGES.
