There are several posts regarding the same, but i still not able to make my expect script work properly. My intention is to automate everything but leave the password enter for the user. So there are 3 parts of the script:
So i have script which will be spawned and which have 3 read commands. First and last should be filled by Expect and second one i would like to enter my self:
#!/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"
My expect script:
#!/usr/bin/expect
spawn ./some_script
expect User
send I-am-expect\r
expect Password
interact
expect Shell
send I-am-expect-again
Unfortunately after i have entered the password the script does not continue and left in the interact mode:
[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>
And finally when i entering something on the "Shell" and pressing [ENTER] expect exits with the error:
Expect entered the command
expect: spawn id exp4 not open
while executing
"expect Shell"
(file "./my-expect" line 7)
[root@localhost ~]#
I appriciate any explanation or resolution of this issue. I am using expect version 5.45
You can read (expect_user
) the user's password by yourself and then send
it to the spawn'ed program. For example:
[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] #
