.TH unget 1
.SH Name
unget \- undo a previous get of an SCCS file
.SH Syntax
.B unget
[\fB\-r\fISID\fR\|] [\fB\-s\fR] [\fB\-n\fR] \fIfiles\fR
.SH Description
.NXR "unget command (sccs)"
.NXR "SCCS file" "ungetting"
The
.PN unget 
command undoes the effect of a
.PN "get \-e"
done prior to creating the intended new delta.
If a directory is named,
.PN unget
behaves as though each file in the directory were
specified as a named file, except that
non-\s-1SCCS\s+1
files and unreadable files are ignored.
If 
.B \-
is given as a name, the standard input is read, with each line
being taken as the name of an SCCS file to be processed.
.SH Options
Keyletter arguments apply independently to each
named file.
.IP \fB\-n\fR 10
Retains copy of SCCS file which normally is removed from current directory.  
.IP \fB\-r\fISID\fR
Indicates delta version number.  
This would have been specified by
.PN get
as the new delta.
The use of this keyletter is necessary only if two or
more outstanding
.PN gets
for editing on the same SCCS
file were done by the same person (login name).
A diagnostic results if the specified
.I \s-1SID\s+1\^
is ambiguous, or if it is necessary and omitted
on the command line.
.IP \fB\-s\fR
Suppresses normal messages, on the standard output
of the intended delta's
.IR \s-1SID\s+1 .
.SH Diagnostics
See
.MS sccshelp 1
for explanations.
