Linux下怎么解壓rar壓縮文件？Linux 系統通常是只支持tar.gz 和gzip 的壓縮包解壓。不支持解壓rar壓縮包的，所以如果需要解壓rar 需要額外安裝一些組件。

1、下載解壓工具包unar

上傳安裝包到/usr/local/src目錄

2、安裝unar工具包

cd /usr/local/src

rpm -ivh libobjc-4.8.5-44.el7.x86_64.rpm

rpm -ivh avahi-libs-0.6.31-20.el7.x86_64.rpm

rpm -ivh wavpack-4.60.1-9.el7.x86_64.rpm

rpm -ivh nettle-2.7.1-8.el7.x86_64.rpm

rpm -ivh trousers-0.3.14-2.el7.x86_64.rpm

rpm -ivh gnutls-3.3.29-9.el7_6.x86_64.rpm

rpm -ivh gnustep-base-libs-1.24.9-1.el7.x86_64.rpm

rpm -ivh unar-1.10.7-1.el7.x86_64.rpm

#yum源安裝

yum install epel-release #需要安裝epel源

yum install unar

3、解壓rar文件

unar file.rar

#Linux解壓縮命令

*.tar.gz后綴 解壓命令：tar -zxv -f file.tar.gz

*.gz后綴 解壓命令：gzip -d file.gz

*.tar.bz2后綴 解壓命令：tar -jxv -f file.tar.bz2

.*bz2后綴 解壓命令：bzip2 -d file.bz2

*.zip后綴 解壓命令：unar file.zip/unzip file.zip

*.rar后綴 解壓命令：unar file.rar

這個時候，Linux就可以解壓rar壓縮文件了。
