NAME

|
|
----
|
||
|
|
pixz - parallel, indexed xz compressor
|
||
|
|
|
||
|
|
SYNOPSIS
|
||
|
|
--------
|
||
|
|
*pixz* ['OPTIONS'] ['INPUT' ['OUTPUT']]
|
||
|
|
|
||
|
|
DESCRIPTION
|
||
|
|
-----------
|
||
|
|
pixz compresses and decompresses files using multiple processors. If the input looks like a tar(1) archive, it also creates an index of all the files in the archive. This allows the extraction of only a small segment of the tarball, without needing to decompress the entire archive.
|
||
|
|
|
||
|
|
OPTIONS
|
||
|
|
-------
|
||
|
|
By default, pixz uses standard input and output, unless 'INPUT' and 'OUTPUT' arguments are provided. If pixz is provided with input but no output, it will delete the input once it's done.
|
||
|
|
|
||
|
|
*-d*::
|
||
|
|
Decompress, instead of compress.
|
||
|
|
|
||
|
|
*-t*::
|
||
|
|
Force non-tarball mode. By default, pixz auto-detects tar data, and if found enters tarball mode.
|
||
|
|
When compressing in non-tarball mode, no archive index will be created. When decompressing, fast extraction will not be available.
|
||
|
|
|
||
|
|
*-l*::
|
||
|
|
List the archive contents. In tarball mode, lists the files in the tarball. In non-tarball mode, lists the blocks of compressed data.
|
||
|
|
|
||
|
|
*-x* 'PATH'::
|
||
|
|
Extract certain members from an archive, quickly. All members whose path begins with 'PATH' will be extracted.
|
||
|
|
|
||
|
|
*-i* 'INPUT'::
|
||
|
|
Use 'INPUT' as the input.
|
||
|
|
|
||
|
|
*-o* 'OUTPUT'::
|
||
|
|
Use OUTPUT as the output.
|
||
|
|
|
||
|
|
*-#*::
|
||
|
|
Set compression level, from -0 (lowest compression, fastest) to -9 (highest compression, slowest).
|
||
|
|
|
||
|
|
*-p* 'CPUS'::
|
||
|
|
Set the number of CPU cores to use. By default pixz will use the number of cores on the system.
|
||
|
|
|
||
|
|
*-h*::
|
||
|
|
Show pixz's online help.
