.SH DESCRIPTION
|
||
|
.LP
|
||
|
This manual page documents the GNU version of
|
||
|
.B tar
|
||
|
, an archiving program designed to store and extract files from
|
||
|
an archive file known as a
|
||
|
.IR tarfile.
|
||
|
A
|
||
|
.IR tarfile
|
||
|
may be made on a tape drive, however, it is also common
|
||
|
to write a
|
||
|
.IR tarfile
|
||
|
to a normal file.
|
||
|
The first argument to
|
||
|
.B tar
|
||
|
must be one of the options:
|
||
|
.BR Acdrtux ,
|
||
|
followed by any optional functions.
|
||
|
The final arguments to
|
||
|
.B tar
|
||
|
are the names of the files or directories which should be archived. The use
|
||
|
of a directory name always implies that the subdirectories below should be
|
||
|
included in the archive.
|
||
|
