Linux - Bash & Expect

问题

I use expect to copy my key to remote linux boxes.

copy_key

#!/usr/bin/expect

stty echo 
set REMOTEhost [lindex $argv 0]
set REMOTEpass [lindex $argv 1]

spawn ssh-copy-id -i /home/myuser/mykey.pub root@$REMOTEhost

expect "password: "

send "$REMOTEpass\n"

sleep 2

This is called via ./copy_key 1.1.1.1 GENERATED_PASSWORD

I'd like to migrate all of this to a bash script.

Something like the following, which of course is something different but just to help with an idea:

#!/bin/bash
/usr/bin/expect -c 'expect "\n" { eval spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no usr@$myhost.example.com; interact }'

This doesnt work

#!/bin/bash
ssh-copy-id -i /home/myuser/mykey.pub root@$REMOTEhost

How can I do that?

回答1:

This would be the 1:1 bash script:

#!/bin/bash
stty echo && expect -c "spawn ssh-copy-id -i /home/myuser/mykey.pub root@$1; expect \"password: \"; send \"$2\r\"; sleep 2;"
