osx 实现一条命令登录ssh

先确保你安装了：expect

brew install expect

然后保存下面的脚本到 /usr/local/bin/ssh.sh

给这个文件执行权限 chmod a+x /usr/local/bin/ssh.sh

#!/usr/bin/expect

# 设置变量
set timeout 20
set port [lindex $argv 0]
set user [lindex $argv 1]
set host [lindex $argv 2]
set password [lindex $argv 3]

# 启动SSH进程
spawn ssh -p $port $user@$host

# 处理可能出现的提示
expect {
    "Are you sure you want to continue connecting (yes/no)?" {
        send "yes\r"
        expect "password:"
        send "$password\r"
    }
    "password:" {
        send "$password\r"
    }
}
