PIXZ(1) ======= :doctype: manpage 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. EXAMPLES -------- `pixz < myfile > myfile.xz`:: Compress a file with pixz. `pixz myfile`:: Compress to myfile.pxz, removing the original. `tar -Ipixz -cf output.tpxz directory`:: Make tar use pixz for compression. `pixz -x path/to/file < input.tpxz | tar x`:: Extract one file from an archive, quickly.
