Convert a Redhat Script to Debian

I would like to convert to following script to use in another environment - Debian.

Yum is not available in Debian and I'm not sure about the rest.

#!/bin/bash
for i in $(seq 1 10)
do
  ip=192.168.1.$i
  host=$(ssh $ip -C hostname 2>&1) 
  echo "====================================================="
  echo "Host $host at IP $ip returned the follow result"
  echo "====================================================="
  ssh $ip "yum list updates" 
done > report_file 2>&1
 
# do something with 'report_file' here...

Try replacing line 9 with this:

ssh $ip "apt-get -s upgrade"

Wait...

Might will probably want to run 'apt-get update' first if you don't already via Cron. It grabs the updated package lists.

Thanks Syngin9 - that get's me much further.

So here is the current script, and it works for the 1st IP, but then seems to fail on the next and is looking for password again. For each machine, I am entering the password manually as it logs on, and then again for sudo, but not sure why it fails on the subsequent IP's.

Here is the output from the script:

How can I rewrite this second script so that it prompts me for the password on the screen (instead of printing it in the report) and continues down the line for each system?
