Expect command scripting language combat

I. Expect implement auto-fill password

1.VI ssh.exp.201

#!/usr/bin/expect

Spawn ssh-p 20000 [email protected]/sbin/ifconfig eth0
Set Timeout 60
Expect "*password:"
Send "abcdef\n"
Expect EOF
Exit

2.chmod ssh.exp.201 #注. If you do not have permission to execute, you can expect,700 permissions directly. Prevent other users from viewing passwords in scripts

3. Execution Effect:

./ssh.exp.201
Spawn ssh-p 20000 [email protected]/sbin/ifconfig eth0
[email protected] ' s password:
Eth0 Link encap:ethernet HWaddr 00:0c:29:31:2b:a0

Exp_continue principle, when to prompt input, to match, when the match succeeds, re-enter the expect, a bit like for the continue in the loop, if there is no exp_continue, then the contents of the expect, only one input matches once, No matter how many keywords you have

Argument:

#!/usr/bin/expect

Spawn ssh-p 20000 [email protected].1.201/sbin/ifconfig eth0
Set Timeout 60
Expect {
-timeout 60
"Yes/no" {exp_send "yes\r"; Exp_continue}
"*password:" {exp_send "abcdef\r"}
Timeout {puts "Expect is time out"; Return
}

Expect EOF
Exit
