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.
- -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.
