.TH PXZ 1 "Jun 2010" pxz "Parallel XZ" .SH NAME pxz \- Parallel LZMA compressor compatible with XZ. .SH SYNOPSIS \fBpxz\fR [\fBoptions\fR]... [\fIfile\fR]... .SH DESCRIPTION .B pxz is a compression utility that takes advantage of running XZ compression simultaneously on different parts of an input file on multiple cores and processors. This significantly speeds up compression time. .SH OPTIONS .TP .I "\-v" Be verbose. .TP .I "\-h," "\-\-help" Display help. .TP .I "\-f," "\-\-force" Force operation. .TP .I "\-c," "\-\-stdout" Write results to standard output and don't delete input files. .TP .I "\-k," "\-\-keep" Keep (don't delete) input files. .TP .I "\-T," "\-\-threads" Maximal number of threads to run simultaneously. .TP .I "\-D," "\-\-context\-size" Context size per one thread specified as a multiple of dictionary size for active compression level. .TP .I "\-V," "\-\-version" Display version of PXZ. .SH EXAMPLES .TP pxz file1 file2 Compress file1 and file2 to file1.xz and file2.xz using default settings. .TP pxz -T4 file1 Compress file1 with default compression and maximum of 4 threads. .TP pxz -k -9 file1 Use maximal compression and keep the original file1, use default number of threads. .TP pxz -f -T4 file1 Compress file with default compression and with 4 threads. .TP pxz -kvf -3 -T8 file1 Use -3 compression, keep the original file, use 8 threads and show progress. .TP tar Oc dir1 | pxz -D 12 -cv - > dir1.tar.xz Move dir1 into tar, then compress it with the context of 12 sizes of dictionary per thread, show progress and write result to dir1.tar.xz. .SH "SEE ALSO" .BR xz (1) .SH AUTHOR Jindrich Novy .SH BUGS Report bugs via http://bugzilla.redhat.com/bugzilla/
