The existing XZ Utils provide great compression in the .xz file format, but they produce just one big block of compressed data.
pixz instead produces a collection of smaller blocks which makes random access to the original data possible. This is especially useful for large tarballs.
pixz is pronounced pixie.
Key Features
- Automatically indexes tarballs during compression.
- Supports parallel decompression and indexed access to compressed data.
- Defaults to using all available CPU cores, while xz defaults to using only one core.
- Keep input (-k) command line option.
- Automatically writes to STDOUT.
- File permission preserved when compressing/decompressing.
