pigz

可以用来解压缩文件，gzip的并行实现升级版

语法

 pigz [ -cdfhikKlLmMnNqrRtz0..9,11 ] [ -b blocksize ] [ -p threads ] [ -S suffix ] [ name ...  ] unpigz [ -cfhikKlLmMnNqrRtz ] [ -b blocksize ] [ -p threads ] [ -S suffix ] [ name ...  ]

参数

 -0 to -9, -11       # Compression level (level 11, zopfli, is much slower) --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 -J, --maxsplits n   # Maximum number of split blocks for -11 -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, --no-time       # Do not store or restore mod time -M, --time          # Store or restore mod time -n, --no-name       # Do not store or restore file name or mod time -N, --name          # Store or restore file name and mod time -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 -v, --verbose       # Provide more verbose output -V  --version       # Show the version of pigz -Y  --synchronous   # Force output file write to permanent storage -z, --zlib          # Compress to zlib (.zz) instead of gzip format --                  # All arguments after "--" are treated as files

实例

可以结合tar使用, 压缩命令

 tar -cvf - dir1 dir2 dir3 | pigz -p 8 > output.tgz

解压命令

 pigz -p 8 -d output.tgz

如果是gzip格式，也支持用tar解压

 tar -xzvf output.tgz
