# xz > Compress or decompress XZ and LZMA files. > More information: . - Compress a file using xz: `xz {{path/to/file}}` - Decompress an XZ file: `xz {{[-d|--decompress]}} {{path/to/file.xz}}` - Compress a file using lzma: `xz {{[-F|--format]}} lzma {{path/to/file}}` - Decompress an LZMA file: `xz {{[-d|--decompress]}} {{[-F|--format]}} lzma {{path/to/file.lzma}}` - Decompress a file and write to `stdout` (implies `--keep`): `xz {{[-d|--decompress]}} {{[-c|--stdout]}} {{path/to/file.xz}}` - Compress a file, but don't delete the original: `xz {{[-k|--keep]}} {{path/to/file}}` - Compress a file using the fastest compression: `xz -0 {{path/to/file}}` - Compress a file using the best compression: `xz -9 {{path/to/file}}`
