Tips & Notes
Useful tips and points to note when using unxz.
Key Tips
- **Identical to xz -d**: unxz is a symbolic link to xz --decompress and functions exactly the same as xz -d.
- **Original File Deletion**: By default, the original .xz file is deleted after decompression. Use the `-k` or `--keep` option to preserve the original file.
- **Pipeline Usage**: unxz supports standard input/output, making it useful in pipelines. For example, you can use it like `cat file.xz | unxz > file`.
- **Error Handling**: If an error occurs during decompression, unxz returns a non-zero exit code. This can be utilized in scripts for error handling.
