# pxz(1)

Parallel LZMA compressor compatible with XZ.

## NAME

pxz - Parallel LZMA compressor compatible with XZ.

## SYNOPSIS

**pxz** \[**options**\]... \[*file*\]...

## DESCRIPTION

**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.

## OPTIONS

- *-v*

  Be verbose.

- *-h, --help*

  Display help.

- *-f, --force*

  Force operation.

- *-c, --stdout*

  Write results to standard output and don't delete input files.

- *-k, --keep*

  Keep (don't delete) input files.

- *-T, --threads*

  Maximal number of threads to run simultaneously.

- *-D, --context-size*

  Context size per one thread specified as a multiple of dictionary size for active compression level.

- *-V, --version*

  Display version of PXZ.

## EXAMPLES

- pxz file1 file2

  Compress file1 and file2 to file1.xz and file2.xz using default settings.

- pxz -T4 file1

  Compress file1 with default compression and maximum of 4 threads.

- pxz -k -9 file1

  Use maximal compression and keep the original file1, use default number of threads.

- pxz -f -T4 file1

  Compress file with default compression and with 4 threads.

- pxz -kvf -3 -T8 file1

  Use -3 compression, keep the original file, use 8 threads and show progress.

- 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.
