关于相同有几篇文章,但是我仍然无法使我期望的脚本正常工作。我的意图是使所有操作自动化,但保留用户输入的密码。因此,脚本包含3部分:
所以我有将要生成的脚本,并且具有3个读取命令。第一个和最后一个应该由Expect填写,第二个我要输入我自己:
#!/bin/ksh
read user?User:
echo "Expect entered the username $user"
read pass?Password:
echo "User entered the password $pass"
read command?"Shell>"
echo "Expect entered the command $command"
我的期望脚本:
#!/usr/bin/expect
spawn ./some_script
expect User
send I-am-expect\r
expect Password
interact
expect Shell
send I-am-expect-again
不幸的是,在我输入密码后,脚本无法继续运行,并处于交互模式:
[root@localhost ~]# ./my-expect
spawn ./some_script
User:I-am-expect
Expect entered the username I-am-expect
Password:i am user
User entered the password i am user
Shell>
最后,当我在“Shell”上输入内容并按[ENTER]时,期望退出并显示以下错误:
Expect entered the command
expect: spawn id exp4 not open
while executing
"expect Shell"
(file "./my-expect" line 7)
[root@localhost ~]#
我希望对此问题做出任何解释或解决。我正在使用期望版本5.45
最佳答案
您可以自己读取(expect_user
)用户密码,然后将send
密码生成到生成的程序中。例如:
[STEP 101] # cat foo.exp
proc expect_prompt {} \
{
global spawn_id
expect -re {bash-[.0-9]+(#|\$)}
}
spawn ssh -t 127.0.0.1 bash --noprofile --norc
expect "password: "
stty -echo
expect_user -timeout 3600 -re "(.*)\[\r\n]"
stty echo
send "$expect_out(1,string)\r"
expect_prompt
send "exit\r"
expect eof
[STEP 102] # expect foo.exp
spawn ssh -t 127.0.0.1 bash --noprofile --norc
[email protected]'s password:
bash-4.3# exit
exit
Connection to 127.0.0.1 closed.
[STEP 103] #
