- undo a previous get of an SCCS file

用法概要

unget [-ns] [-rsid] s.filename...

描述

The unget utility undoes the effect of a get-e command executed before the creation of the pending delta.

If a directory name is used in place of the s.filename argument, the unget command applies to all s.files in that directory. Unreadable s.files produce an error; processing continues with the next file (if any). The use of `-' as the s.filename argument indicates that the names of files are to be read from the standard input, one s.file per line.

选项

The following options are supported:

-n

Retains the retrieved version, which is otherwise removed.

-s

Suppress display of the SCCS delta ID (SID).

-rsid

When multiple versions are checked out, this option specifies which pending delta to abort. A diagnostic results if the specified SID is ambiguous, or if it is necessary but omitted from the command line.
