By default tarlz creates, lists and extracts archives in a +simplified posix pax format compressed with lzip on a per file basis. Each +tar member is compressed in its own lzip member, as well as the end\-of\-file +blocks. This method adds an indexed lzip layer on top of the tar archive, +making it possible to decode the archive safely in parallel. The resulting +multimember tar.lz archive is fully backward compatible with standard tar +tools like GNU tar, which treat it like any other tar.lz archive. Tarlz can +append files to the end of such compressed archives. .PP The tarlz file format is a safe posix\-style backup format. In case of corruption, tarlz can extract all the undamaged members from the tar.lz @@ -40,6 +42,9 @@ change to directory <dir> \fB\-f\fR, \fB\-\-file=\fR<archive> use archive file <archive> .TP +\fB\-n\fR, \fB\-\-threads=\fR<n> +set number of decompression threads [2] +.TP \fB\-q\fR, \fB\-\-quiet\fR suppress all messages .TP @@ -97,8 +102,8 @@ Report bugs to lzip\-bug@nongnu.org .br Tarlz home page: http://www.nongnu.org/lzip/tarlz.html .SH COPYRIGHT -Copyright \(co 2018 Antonio Diaz Diaz. -Using lzlib 1.11\-rc2 +Copyright \(co 2019 Antonio Diaz Diaz. +Using lzlib 1.11 License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html> .br This is free software: you are free to change and redistribute it. |
