1.说明
要安装一个.rar格式的应用，上传 Linux 系统后发现没有解压工具，上网搜索后开始一波三折的旅程。
2.安装
2.1 跳坑
# 有小伙伴分享安装方法 yum install rar # 安装后根本无法使用 unrar 命令
2.2 一波三折
WinRAR 官网下载 这里有各种操作系统不同语言的版本，下载注意【坑1️⃣】：
# 查询系统版本信息是 x86_64 rpm -qi centos-release Name : centos-release Version : 7 Release : 9.2009.1.el7.centos Architecture: x86_64
查询系统版本信息是x86_64是64 bit 的 x86 指令集系统如果点击RAR 6.11 for Linux x86下载到的rarlinux-x32-611.tar安装包是32 bit的，安装后使用报错：
-bash: /usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
重新下载64 bit的安装包rarlinux-x64-611.tar：
# 解压 安装 tar -zxvf rarlinux-x32-611.tar cd rar make make install
3.使用
【坑2️⃣】安装成功后用了小伙伴举例的解压命令：
# 怎知道这个是 without archived paths unrar e xxx.rar # 带路径的用 unrar x xxx.rar
# 仅贴出两个参数 UNRAR 6.11 freeware Copyright (c) 1993-2022 Alexander Roshal Usage: unrar <command> -<switch 1> -<switch N> <archive> <files...> <@listfiles...> <path_to_extract\> <Commands> e Extract files without archived paths x Extract files with full path
