mac 利用 sshpass 自动登录

mac 利用 sshpass  + 配置文件 实现自动登录 

 使用方式  https://github.com/vipzhicheng/go  参见此项目

其实原理也就是 脚本 读取配置文件 匹配 参数或者 ip 调用 ssh 命令  简单 mark下  

 按照链接方式配置好之后 

shell 中 执行   go (参数) 

例如 我配置

# IP USER:PASS Label

 

120.27.96.210(你的 ip)  你的用户名:你的密码  label:210

执行 go 210 

直接 ssh 登录到 目标 ip  

#!/bin/bash

# Define config directory and config path
GO_HOME=~
AUTHFILE=$GO_HOME/.ssh/pass/.go.conf

# Parse options
while getopts gh ARGS
do
  case $ARGS in 
    g)
   extra_options="-D7070"
    shift
   ;;
    h)
        echo "usage: go [-gh] foo bar"
        exit 0;
    ;;
    *)
        echo "Unknow option: $ARGS"
        echo "usage: go [-gh] foo bar"
        exit 1;
        ;;
  esac
done
