bash scripting : using expect

Question

I am facing an issue when I run simply these commands.

The remote server want to pass "yes" to add the key in RSA file because first time connection established with scp.

commands are given below

#!/bin/bash scp -P58222 root@IP:/root/K /N /usr/bin/expect -c 'expect "\n" { expect "Are you sure you want to continue connecting (yes/no)?" }' send "yes\r" expect "$ " send "exit\r" 

Actually I have to pass yes in my script while showing

Are you sure you want to continue connecting (yes/no)? 

how can i get rid of this problem..?

Answer 1

Instead of scripting the response with expect, just turn off prompting before adding.

scp -o "StrictHostKeyChecking no" ...

Since you're using expect with ssh in the first place, I'll just say that ssh-copy-id to set up passwordless ssh is a much better way to do things.

Answer 2

Here is fragment from my working script.

 send_user "FILE \"FILETEMPL\" is copied to active.\n" spawn scp -l 60 FILETEMPL root@IP:PATHTEMPL/FILETEMPL # After scp we should wait "#" or "100%". set timeout 600 expect { "password: " { send "PASS\r" expect { "100% " {...} "password: " { .. } timeout { ... } } } timeout { exit 1 } eof { exit 2 } }
