利用Linux的shell脚本sshWindows执行命令不成功
利用Linux的shell脚本sshWindows执行命令不成功写了一个自动备份数据库的脚本，但每天查看结果都比较麻烦，就想写一个自动提示的脚本，而且是从虚机的linux直接发送提示到物理机的Windows，利用msg弹窗，具体脚本如下：
<p>#!/usr/bin/expect
set timeout 30
set host "192.168.104.223"
set username "administrator"
set password "123"</p><p>spawn ssh <a href="mailto:$username@$host">$username@$host</a>
expect "*password*" {send "$password\r"}
expect "*Administrator*" {send "cmd\r"}
expect "*Administrator*" {send "msg /server:$host * 已完成昨日MySQL数据库备份\r"}
expect "*Administrator*" {send "exit\r"}
expect "*Administrator*" {send "exit\r"}
expect "*Administrator*" {send "exit\r"}</p><p>如果我根据脚本的步骤手动去敲命令，物理机的Windows可以正常出现提示框，但写入到脚本之后就不行了，也不知道具体原因是什么，执行后如下所示：</p><p>@test_server shell]# ./windowspasswd.sh
spawn ssh <a href="mailto:administrator@192.168.104.223">administrator@192.168.104.223</a></p><p> ****USAGE WARNING****</p><p>This is a private computer system. This computer system, including all

按脚本来走的话，最后Windows应该是成功出现弹窗，同时命令行退回到Linux才对啊。但实际到上面哪里就卡住不动了，也没有弹窗，也没有退回Linux。</p>
权限是否正确 权限是否正确 应该是权限不够导致，先排查一下这个原因 权限不够，增加权限
