unget - Cancels a previous get command
unget [-n] [-s] [-r SID] file... | -
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.
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 pfile
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.
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.
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 sfiles,
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.
The following exit values are returned. Successful completion.
An error occurred.
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 [Toc] [Back] 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 implementationspecific
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.
