看看 expect 执行，结果不能自动登录，提示invalid command name "~"

    当时生产秘钥是，是技术部给分配的。我不知道。所以只能在通过上面你说的这个方法了，对吗

我没有“send "sh /data/tool/sync/web.sh\r"” 是不是需要再创建秘钥

这是我执行的命令，登录上去，总要操作点东西吧。你随便写个命令就OK。

#!/usr/bin/expect -f
set ip l-hs01.wap.cn1
set pw "v^@*8#3k8^z-@;~"
spawn ssh  abel.li@$ip
        expect {
                "want"        {send -- "yes\r"; exp_continue}
                "password:"   {send -- $pw\r}
                "No route"    { exit }

#        expect  "*#"
        expect "]#"
        send "pwd\r"
        expect "]#"
        send "exit\r"
然后在执行时，结果是这样，还是停留在本地机器上

我对expect不熟悉，不对我提供的那个脚本，在我机子上运行正常。登录到远程机子，执行命令，然后再退回本地。

-d debug看一下结果

#这部分应该是你ssh过去后的，没人任何output.

Enter passphrase for key '/home/q/home/abel.li/.ssh/id_rsa':
这个是终端输出，

expect: does "Enter passphrase for key '/home/q/home/abel.li/.ssh/id_rsa': " (spawn_id exp6) match glob pattern "want"? no
"password:"? no
"No route"? no
expect: timed out
是否匹配你的设定want/password/No route，没有一个匹配上。

expect: does "Enter passphrase for key '/home/q/home/abel.li/.ssh/id_rsa': " (spawn_id exp6) match glob pattern "]#"? no
expect: timed out

也不匹配]#

输出是Enter passphrase for key '/home/q/home/abel.li/.ssh/id_rsa':

应该写成expect "Enter"
            send 你的密码

expect是一问一答形式，比如终端输出是Hello xxxx, 那你要捕获的是hello xxx的任意字符。然后send对应的答案。 你man expect看下关于expect的大概说明，然后结合这个debug看下就明白了。

   expect {
                "want"        {send -- "yes\r"; exp_continue}
                "password:"   {send -- $pw\r}
                "No route"    { exit }
                }

这部分没任何作用了，因为你设了passphase，不可能有这个are you sure you want to continue或者passowrd 这种输出了，所以你expect捕获不到的。
