NAME
pixz - parallel, indexing version of XZ
SYNOPSIS
/usr/bin/pixz input output.pxz
/usr/bin/pixz -d input.pxz output
/usr/bin/pixz -l input.tpxz
/usr/bin/pixz -x /path/to/file < input.tpxz
DESCRIPTION
The existing XZ Utils ( http://tukaani.org/xz/ ) provide great compres-
sion in the .xz file format, but they have two significant problems:
o They are single-threaded, while most users nowadays have
multi-core computers.
o The .xz files they produce are just one big block of com-
pressed data, rather than a collection of smaller blocks.
This makes random access to the original data impossible.
With pixz, both these problems are solved.
EXAMPLES
Specifying input and output:
$ pixz < foo.tar > foo.tpxz
Same as 'pixz foo.tar foo.tpxz'
$ pixz -i foo.tar -o foo.tpxz
Ditto. These both work for -x, -d and -l too, eg:
$ pixz -x -i foo.tpxz -o foo.tar file1 file2 ...
# Extract the files from foo.tpxz into foo.tar
$ pixz foo.tar
Compress it to foo.tpxz, removing the original
$ pixz -d foo.tpxz
Extract it to foo.tar, removing the original
OPTIONS
-1 Faster, worse compression.
-9 Better, slower compression.
-p <number>
Cap the number of threads at <number>.
-t Compress but don't treat it as a tarball (don't index it).
-d Decompress, don't check that contents match index.
-l List the xz blocks instead of files.
WARNING
Running pixz without the -t flag will cause it to treat the input as a
tarball, as long as it looks vaguely tarball-like. This means if the
file starts with at least 1024 zero bytes, pixz will assume it's empty,
and truncate the output! If your input files aren't tarballs, run with
-t or face possible data-loss.
