Shell Programming and Scripting

Hi,

I am writing a script to enter into a list of servers and take the backup of the cronjobs on that servers...

==============================
[CODE]-bash-3.00$ expect spawn.exp ssh rcdn6-vm59-33
spawn ssh servers1 /CODE]====================

Code:

-bash-3.00$ cat spawn.exp
#!/usr/bin/expect
eval spawn $argv
expect "$"
send "crontab -l >> /tmp/cronjob"
expect "$"

===================================

***Can you suggest me the commands in the spawn.exp which needs to be used for a graceful exit after executing the commands.

I am calling spawn.exp from other script where i filter all the hostnames from the file as given below.
============================================

Code:

-bash-3.00$ cat main.sh
#!/bin/bash
FILENAME=servers.txt
count=0
hostnam=`hostname`
echo $hostnam
cat $FILENAME | while read LINE
do
let count++
echo "$count $LINE"
expect -f spawn.exp ssh $LINE
done

-bash-3.00$

======================================================

I got it solved by using this script....i think my prompt wasn't correct..now its working fine..

Code:

-bash-3.00$ cat spawn.exp
#!/usr/bin/expect
set prompt "(%|#|\\$|%\]) $"
eval spawn $argv
expect -re "$prompt"
send "sleep 5\r"
expect -re "$prompt"
send "crontab -l >> /tmp/cronjob\r"
expect -re "$prompt"
send  "exit\r"

Add a cron job to each server, to have it save the cron info periodically, Date-time in file name.
