linux 中文件利用管道进行压缩输出

 

1、

root@DESKTOP-1N42TVH:/home/test# ls
outcome.map
root@DESKTOP-1N42TVH:/home/test# wc -l outcome.map    ## 测试文件
46827 outcome.map
root@DESKTOP-1N42TVH:/home/test# head -n 10 outcome.map | gzip > xxx.map.gz     ## 文件的压缩输出
root@DESKTOP-1N42TVH:/home/test# ls
outcome.map  xxx.map.gz
root@DESKTOP-1N42TVH:/home/test# gzip -dc xxx.map.gz > xxx.map   ## 解压缩并保留原始文件
root@DESKTOP-1N42TVH:/home/test# ls
outcome.map  xxx.map  xxx.map.gz
root@DESKTOP-1N42TVH:/home/test# cat xxx.map   ## 解压后查看结果
