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:  XPG4, XPG4-UNIX

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. 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. 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. Suppresses displaying the deleted SID.
 

OPERANDS

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.

[Compaq]  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. Successful completion. An error occurred.
 

EXAMPLES

To discard the changes you have made to an SCCS file after doing a get -e, enter: unget s.prog.c 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: 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. If set to a non-empty string value, overrides the values of all the other internationalization variables. 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). Determines the locale that should be used to affect the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MESSAGES.
