DESCRIPTION

The unget command allows you to restore a g-file created with a get -e before
the new delta is created, and therefore discarding the changes (see "get" and
"delta").  If you specify a - (hyphen) 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.  The unget command continues to take input
until it reaches an end of file character, which is a Ctrl-D if input is from
the keyboard.

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

FLAGS

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

-n       Prevents the automatic deletion of the g-file.  This flag allows you
         to retain the edited version of the file without making a delta.

-rSID    Specifies 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.

-s       Suppresses writing the deleted SID to standard output.
