Expect script for pushing out cron
 

Hi!



I am in need of an expect script to update cron on multiple hosts. Expect is installed on the system and I am hoping if someone has a handy script already, to update cron on multiple hosts from an admin host, please share.



Thanks,
Allan.

You shouldn't need an expect script. Just setup public key authentication for ssh.

Then you can just do "cat new-cron-file | ssh <remote> crontab"

IF you are dealing with a cluster, use the cluster tools to distribute the update.

Hi!

I dont have sshkeyless setup on hundreds of hosts.

Do need expect script to work for now.

Thanks,
Allan.

for j in `cat host-list`
do
expect -f /tmp/sshlogin.expect
done

can't read "j": no such variable
while executing
"spawn ssh -n username@$j 'crontab -l | tee /tmp/info'"
(file "/tmp/sshlogin.expect" line 2)

I think you will have to export j to make it available in the environment.

Putting a public key on each system is safer than embedding a script with your password.
