linux使用pigz多线程压缩

因为tar zip是单线程的压缩，压缩起来很慢，这个使用使用pigz工具辅助就会使用多线程了。

安装

sudo apt install pigz

压缩

tar cvf - test.txt | pigz > test.tar.gz

解压到指定目录

1.  
   I found three solutions:
2.  
   With GNU tar, using the awesome -I
3.  
   option:
4.  
   tar -I pigz -xvf /path/to/archive.tar.gz -C /where/to/unpack/it/
5.  
    
6.  
   With a lot of Linux piping (for those who prefer a more geeky look):
7.  
   unpigz < /path/to/archive.tar.gz | tar -xvC /where/to/unpack/it/
8.  
    
9.  
   More portable (to other tar
10.  
    implementations):
11.  
    unpigz < /path/to/archive.tar.gz | (cd /where/to/unpack/it/ && tar xvf -)
12.  
     
13.  
    (You can also replace tar xvf -
14.  
    with pax -r
15.  
    to make it [POSIX](https://en.wikipedia.org/wiki/POSIX)-compliant, though not necessarily more portable on Linux-based systems).
16.

使用tar+pigz+ssh实现大数据的高效传输, 流式压缩传输

磁盘读取---->打包---->压缩------>传输---->解压缩-->拆包---->落盘
|->tar |->gzip |->ssh |->gzip |->tar
tar -c test/ |pigz |ssh -c arcfour128 目标IP "gzip -d|tar -xC /data" # 解压
tar -c test/ |pigz |ssh -c arcfour128 目标IP "cat >/data/test.tar.gz" # 不解压
