Expect script error send: Spawn id exp4 not open while executing
I'm trying to run this script but having different errors when modified. Here is the code and the output. Please help.
Updates at the end of the post with debug info
#!/bin/bash
(( $# != 1 )) && { echo >&2 "Usage: $0 \"[COMMAND]\""; exit 1; }
servers_addresses=(10.10.10.10 )
for server_address in ${servers_addresses[@]}; do
expect <<EOF
spawn ssh -t root@$server_address "$*"
expect -timeout 2 "Are you sure you want to continue connecting (yes/no)?" { send "yes\n" }
expect "s password:" { send "Correct_Password\n" }
expect "s password:" { send "Wrong_Password_22222\n" }
expect "s password:" { send "Wrong_Password_33333\n" }
expect eof
EOF
done
And the output is like:
goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts"
spawn ssh -t [email protected] sudo cat /etc/hosts
[email protected]'s password:
# Do not remove the following line, or various programs
# that require network functionality will fail.
10.10.10.10 TEST-004 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Connection to 10.10.10.10 closed.
expect: spawn id exp4 not open
while executing
"expect "s password:" { send "Wrong_Password_33333\n" }"
If I modify like this, then the output would be bit different
expect "s password:" { send "Wrong_Password_11111\n" }
expect "s password:" { send "Correct_Password\n" }
expect "s password:" { send "Wrong_Password_33333\n" }
goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts"
spawn ssh -t [email protected] sudo cat /etc/hosts
[email protected]'s password:
# Do not remove the following line, or various programs
# that require network functionality will fail.
10.10.10.10 TEST-004 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Connection to 10.10.10.10 closed.
expect: spawn id exp4 not open
while executing
"expect eof"
And if the correct password in on the third line then no errors at all. Works fine on this one.
expect "s password:" { send "Wrong_Password_11111\n" }
expect "s password:" { send "Wrong_Password_22222\n" }
expect "s password:" { send "Correct_Password\n" }
goldberg188@Test-Server ~$ ./test.sh "sudo cat /etc/hosts"
spawn ssh -t [email protected] sudo cat /etc/hosts
[email protected]'s password:
# Do not remove the following line, or various programs
# that require network functionality will fail.
10.10.10.10 TEST-004 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Connection to 10.10.10.10 closed.
Ignore the Edits: I know how to run 2 commands at once.

Solution 1:
Assuming you're not sending a wrong password on purpose, use exp_continue
as a looping construct:
expect <<EOF
set passwds {foo bar baz}
set i 0
spawn ssh -t root@$server_address "$*"
expect {
"continue connecting (yes/no)?" { send "yes\r"; exp_continue }
" password: " { send "[lindex $passwds $i]\r"; incr i; exp_continue }
eof
}
EOF
