前言

每次想登录一台吃灰的服务器的时候，都要想半天 host + password（找各种备忘录），于是乎想写一个小脚本来管理它们，虽然通过编辑 /.ssh/config 文件也可以实现类似功能，但是每次添加或者查看都还是需要去 cd xxx & vim xxx，作为 新脚本小子，肯定得更 优雅 一点才行。

global use

cp sshm.sh /usr/local/bin/sshm
# use just like:

add

sshm add

sshm ls

login server

sshm server_name

delete

sshm rm server_name
