pxz - Man Page

pxz [options]... [file]...

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.

-v

Be verbose - shows progress.

-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.

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.
