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 |
