tar
.Lbzip2
is a multithreaded utility for handling
‘bzip2’ compression, written by Laszlo Ersek. It makes use of
multiple processors to speed up its operation and in general works
considerably faster than bzip2
. For a detailed description
of lbzip2
see http://freshmeat.net/projects/lbzip2 and
lbzip2: parallel bzip2 utility.
Recent versions of lbzip2
are mostly command line compatible
with bzip2
, which makes it possible to automatically invoke
it via the --bzip2 GNU tar
command line option. To do so,
GNU tar
must be configured with the --with-bzip2 command
line option, like this:
$ ./configure --with-bzip2=lbzip2 [other-options]
Once configured and compiled this way, tar --help
will show the
following:
$ tar --help | grep -- --bzip2 -j, --bzip2 filter the archive through lbzip2
which means that running tar --bzip2
will invoke lbzip2
.
