linux中默认的tar命令用于解压压缩文件，但是tar命令不支持rar文件的解压和压缩，需要安装rar解压工具，实现rar命令解压rar压缩包。

1.下载rarlab软件wget -c https://www.rarlab.com/rar/rarlinux-x64-5.5.0.tar.gz

2.解压和安装rar工具tar -xzvf rarlinux-x64-5.5.0.tar.gz

#加压后生产rar目录

cd rar

[root@localhost rar]# ls

acknow.txt  default.sfx  license.txt  makefile  order.htm  rar  rarfiles.lst  rar.txt  readme.txt  unrar  whatsnew.txt

[root@localhost rar]# make && make install

mkdir -p /usr/local/bin

mkdir -p /usr/local/lib

cp rar unrar /usr/local/bin

cp rarfiles.lst /etc

cp default.sfx /usr/local/lib

mkdir -p /usr/local/bin

mkdir -p /usr/local/lib

cp rar unrar /usr/local/bin

cp rarfiles.lst /etc

cp default.sfx /usr/local/lib

3.使用 rar压缩 unrar解压文件#压缩

[root@localhost rar]# rar a all *
