Creating an archive is only half the job—there is no point in storing
files in an archive if you can't retrieve them. The act of retrieving
members from an archive so they can be used and manipulated as
unarchived files again is called extraction. To extract files
from an archive, use the --extract (--get or
-x) operation. As with --create, specify the name
of the archive with --file (-f) option. Extracting
an archive does not modify the archive in any way; you can extract it
multiple times if you want or need to.
Using --extract, you can extract an entire archive, or specific
files. The files can be directories containing other files, or not. As
with --create (-c) and --list (-t), you may use the short or the
long form of the operation without affecting the performance.
