荐一个获取Linux服务器（ubuntu、centos已测试）信息的Shell脚本

本文我们来分享一个获取Linux服务器信息的Shell脚本,此脚本已在ubuntu、centos测试通过,本文脚本可以获取Linux发行版本,操作系统是不是64位的.

此脚本已经在ubuntu以及centos版本上测试通过,直接上源代码比较爽:

1. #!/bin/bash
3. Line='==========='
5. #linux发行版名称
6. if[[-f/usr/bin/lsb_release]];then
7. OS=$(/usr/bin/lsb_release-a|grepDescription|awk-F:'{print$2}'|sed's/^[t]*//g')
8. else
