常用示例
View contents
xzcat [file.xz]
View contents of a .lzma file
xzcat [file.lzma]
Pipe to another command
xzcat [file.xz] | grep "[pattern]"
Test file integrity
xzcat -t [file.xz]
Verbose output
xzcat -v [file.xz]
Decompress multiple files
xzcat [file1.xz] [file2.xz]
说明
xzcat decompresses .xz and .lzma files and writes the uncompressed data to standard output. It is equivalent to running xz --decompress --stdout or xz -dc. The XZ format uses LZMA2 compression algorithm and provides better compression ratios than gzip or bzip2, though at the cost of slower compression speed. Decompression is relatively fast. xzcat reads from standard input if no files are specified or if - is given as a filename.
参数
- -f, --force
- Force decompression even if input doesn't appear to be in .xz format.
- -k, --keep
- Keep input files (they're not deleted anyway with xzcat).
- -t, --test
- Test compressed file integrity without outputting data.
- -q, --quiet
- Suppress warnings and non-fatal error messages.
- -v, --verbose
- Display filename and statistics during processing.
- --memlimit=_limit_
- Set memory usage limit for decompression.
- --format=_format_
- Restrict to specific format: xz, lzma, raw, auto.
- -h, --help
- Display help message and exit.
- -V, --version
- Display version information and exit.
