NAME

unget - Cancels a previous get command

SYNOPSIS

unget [-n] [-s] [-rSID] file ...  | -

The unget command allows you to 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). 

FLAGS

Each flag or group of flags applies independently to each named file. 

-nPrevents the automatic deletion of the file obtained by get,the g-file.  This flag allows you to retain the edited version of the file without making a delta. 

-rSIDSpecifies the new delta that would have been created by the next use of the delta command.  You must use this flag 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. 

-sSuppresses displaying the deleted SID. 

DESCRIPTION

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. 

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.  If you specify a directory in place of file, unget performs the requested actions on all SCCS files (those files with the s. prefix). 

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:

LANGProvide 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 contains an invalid setting, the utility behaves as if none of the variables had been defined. 

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

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

|∗LLC_MESSAGES
Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.

NLSPATH
Determine the location of message cataloues for the processing of LC_MESSAGES. 

EXIT STATUS

The following exit values are returned. 

0Successful completion. 

>0An error occurred.
