shell pigz高效压缩解压命令

命令详解

pigz 高效多线程，可代替gzip

# 压缩：pigz：用法-9是压缩比率比较大，-p是指定cpu的核数。
tar cvf - mydir | pigz -9 -p 24 > file.tgz

# 解压: 
pigz -d  file.tgz
pigz -dc  file.tgz  # cat的形式打印出来
unpigz file.gz

Options:
  -0 to -9, -11        Compression level (11 is much slower, a few % better)
  --fast, --best       Compression levels 1 and 9 respectively
  -b, --blocksize mmm  Set compression block size to mmmK (default 128K)
  -c, --stdout         Write all processed output to stdout (won't delete)
  -d, --decompress     Decompress the compressed input
  -f, --force          Force overwrite, compress .gz, links, and to terminal
  -F  --first          Do iterations first, before block split for -11
  -h, --help           Display a help screen and quit
  -i, --independent    Compress blocks independently for damage recovery
  -I, --iterations n   Number of iterations for -11 optimization
  -k, --keep           Do not delete original file after processing
  -K, --zip            Compress to PKWare zip (.zip) single entry format
  -l, --list           List the contents of the compressed input
  -L, --license        Display the pigz license and quit
  -M, --maxsplits n    Maximum number of split blocks for -11
  -n, --no-name        Do not store or restore file name in/from header
  -N, --name           Store/restore file name and mod time in/from header
  -O  --oneblock       Do not split into smaller blocks for -11
  -p, --processes n    Allow up to n compression threads (default is the
                       number of online processors, or 8 if unknown)
  -q, --quiet          Print no messages, even on error
  -r, --recursive      Process the contents of all subdirectories
  -R, --rsyncable      Input-determined block locations for rsync
  -S, --suffix .sss    Use suffix .sss instead of .gz (for compression)
  -t, --test           Test the integrity of the compressed input
  -T, --no-time        Do not store or restore mod time in/from header
  -v, --verbose        Provide more verbose output
  -V  --version        Show the version of pigz
  -z, --zlib           Compress to zlib (.zz) instead of gzip format
  --                   All arguments after "--" are treated as files
