# XZ Compression
|
|
XZ is a general-purpose data compression tool that belongs to the family of LZ77-based compressors. It provides high compression ratios and fast decompression, making it suitable for various applications. XZ uses the LZMA2 compression algorithm, which is an improved version of LZMA.

|
|
|
## Usage
|
|
Usage: `xz [OPTION]... [FILE]...`
|
|
|
|
### Options
|
|
| Option | Description |
|
|
| ------------------- | ---------------------------------------------------------------------------------------------------------------- |
|
|
| `-z, --compress` | force compression |
|
|
| `-d, --decompress` | force decompression |
|
|
| `-t, --test` | test compressed file integrity |
|
|
| `-l, --list` | list information about .xz files |
|
|
| `-k, --keep` | keep (don't delete) input files |
|
|
| `-f, --force` | force overwrite of output file and (de)compress links |
|
|
| `-c, --stdout` | write to standard output and don't delete input files |
|
|
| `-0 ... -9` | compression preset; default is 6; take compressor *and* decompressor memory usage into account before using 7-9! |
|
|
| `-e, --extreme` | try to improve compression ratio by using more CPU time; does not affect decompressor memory requirements |
|
|
| `-T, --threads=NUM` | use at most NUM threads; the default is 1; set to 0 to use as many threads as there are processor cores |
|
|
| `-q, --quiet` | suppress warnings; specify twice to suppress errors too |
|
|
| `-v, --verbose` | be verbose; specify twice for even more verbose | |
