linux中rar文件的压缩、解压

1、测试数据

root@ubuntu01:/home/test# ls
outcome.map  outcome.ped
root@ubuntu01:/home/test# ll -h
total 80M
drwxr-xr-x 2 root root 4.0K 3月  27 15:58 ./
drwxr-xr-x 6 root root 4.0K 3月  27 14:36 ../
-rw-r--r-- 1 root root 1.3M 10月 15  2018 outcome.map
-rw-r--r-- 1 root root  79M 10月 19  2018 outcome.ped

 

2、压缩为rar文件

root@ubuntu01:/home/test# ls
outcome.map  outcome.ped
root@ubuntu01:/home/test# rar a xxx.rar outcome.*    ## 压缩为rar文件
