finalshell查看连接远程linux的用户名和密码

本文主要是介绍finalshell查看连接远程linux的用户名和密码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

使用finalshell去连接linux,由于用户名和密码输入一次后，下次finalshell会替我们记住密码。接着，时间久了，密码忘了。
以mac为例，密码存放在/Users/$USER/Library/FinalShell/conn文件中，密码以密文形式保存。比如我的主机名叫"shuangyueliao.cn"，查看主机对应密码,在conn目录下执行
grep -rni "shuangyueliao.cn" *

把密码放到下面文件中s1位置并执行，就能得到解密后的密码
