对于ubuntu中rar文件操作攻略
首先说明，此方法为习惯命令行方式的用户写的，如果你不喜欢使用command line的话，请不要浪费时间住下读了。
rar 是源于 windows 的压缩格式， linux 对它们的支持并不像 tar 或者 gzip 那样理所当然，因此，当你在 ubuntu 下无法避开这两种压缩格式的文件时，你必须安装额外的工具软件来解开这些压缩文件。
安装 rar 解压缩文件：
sudo apt-get install rar
解压缩 rar 文件：
rar e myfile.rar
下面是利用
rar > rar.txt
命令得到的rar命令的说明文档，供有需要的同志参考。
