Tcl Expect脚本在“新建密码”提示下无误结束

我有Solaris服务器，我不确定是否已将其密码更改为特定帐户。我将成功地进行身份验证，因为我已经更改了密码，或者我将使用旧密码进行身份验证，它将在我使用旧密码进行身份验证后提示我更改密码，因为旧密码已过期

Warning: Your password has expired, please change it now.
New Password: 

脚本将在

新密码：

提示下停止，并在没有错误的情况下退出

#!/bin/bash

NewPassword="cccccc"
OtherPassword="ffffffff"

for i in `cat x.txt`

do

/opt/csw/bin/expect -f  <(cat << EOF

spawn ssh -o StrictHostKeyChecking=no adminuser@$i
expect "Password: "
send "$NewPassword\r"

expect {
"$ " { 
## new password worked 
     send "uname -a\r"
}
"Password: " {
 ## The new password did not work 
    send "$OtherPassword\r"
    expect "$ "
}
"New Password: " {
 ## after authenticating, my old password expired need to change it now
    send ${NewPassword}\r
    expect "Re-enter new Password: "
    send ${NewPassword}\r
    expect "$ "
}
}
EOF
)
done

#/bin/bash
NewPassword=“CCCC”
OtherPassword=“ffffffff”
因为我在'cat x.txt`
做
/opt/csw/bin/expect-f条款在
expect
事件中的顺序；内部匹配器将按照指定的顺序尝试不同的匹配规则。这在这里很重要，因为
密码：
的规则也匹配
新密码：
将匹配的内容，因此优先于它

交换两个子句或重写它们，使它们不能同时匹配相同的输入文本（可能包括换行符或更改为使用锚定正则表达式）。交换它们要容易得多。
除了Donal令人信服的建议之外，还有几个注意事项：

在shell部分中，不要阅读带有
的行

使用流程替换和
cat
以及here文档是过分的：您只需要here文档
使用
exp\u continue
处理在看到提示之前发生的异常情况
退出您的登录会话，并期望看到它关闭，这样您就不必等待超时
#/bin/bash
NewPassword=“CCCC”
OtherPassword=“ffffffff”
读服务器时；做
/opt/csw/bin/expect为什么我问这个问题会被责骂。
#!/bin/bash
NewPassword="cccccc"
OtherPassword="ffffffff"
