Bash script does not ssh all the entries of a csv file

I am trying to patch a bunch of CENT OS machines with the latest fix pack. I have the below bash script that takes csv file as a input which has the ip address and password

Answer 1

You can pass ssh another -t to force pty allocation:

ssh -t -t

Answer 2

Add at the end of your sshpass command </dev/null.

Answer 3

1. Add Defaults:username !requiretty to your /etc/sudoers config
2. Get rid of -t from your ssh command
3. Optional, but recommended: set up public key auth so you don't have your passwords lying around in text files.
