网上下载rar 压缩文件的使用，在linux在我们需要对其进行解压缩，这个时候，我们需要安装 rar相关的文件，来进行解压缩。

1. 下载

我们进入rarlab网站，进行下载 rar for linux x64

2. 使用 tar 命令 解压 （*.tar 用 tar –xvf ）

➜  Downloads tar -xvf rarlinux-x64-5.6.0.tar.gz

3. 进入文件夹make (需要 管理员权限)

➜  rar cat makefile 
###################################################################
# Installing RAR executables, configuration files and SFX modules #
# to appropriate directories                                      #
###################################################################

PREFIX=/usr/local

install:
    mkdir -p $(PREFIX)/bin
    mkdir -p $(PREFIX)/lib
    cp rar unrar $(PREFIX)/bin
    cp rarfiles.lst /etc
    cp default.sfx $(PREFIX)/lib%

如果不进行make 需要在命令所在的文件夹执行命令，或者把文件夹加入环境变量中。

3. 最后，可以使用 unrar 进行解压， 使用 rar 命令，进行压缩。

➜  ~ unrar x [file]

我们 可以直接输入 unrar 查看帮助

➜  rar ./unrar
