常用示例
Decompress file
unxz [file.xz]
Keep original
unxz -k [file.xz]
To stdout
unxz -c [file.xz]
Force overwrite
unxz -f [file.xz]
Decompress multiple
unxz [file1.xz] [file2.xz]
说明
unxz decompresses files that were compressed with the XZ format, which uses the LZMA2 algorithm for high compression ratios. It is functionally equivalent to running xz --decompress and is provided as a convenience command within the xz-utils package. By default, unxz replaces the compressed .xz file with the decompressed output, removing the original. The -k flag preserves the original compressed file, and -c writes decompressed data to standard output for piping to other commands. XZ is widely used in the Linux ecosystem for distributing source code tarballs, kernel sources, and package archives due to its excellent compression ratio. While decompression is fast, XZ compression is slower and more memory-intensive than alternatives like gzip or zstd.
