SSH Script

ntbluez · 02-07-2016, 05:26 PM

Wrote SSH script.
It seems to be running, connecting to servers in my server list file via SSH. Problem is, I cannot see the session or prompt to see password input...

Something about running ssh in script needs to be >/dev/null 2>%1 ???

Please help

Code:

#!/bin/bash
SERVERS=servers
for SERVERS in 'cat servers'
do
ssh MyUserName@$SERVERS df -h
done

Nope, you don't need to redirect anything.
It could be that you are using single quotes instead of backticks. Since you're using bash, you should use $(cat servers) instead.

If you're looking for other tips. The line beginning with SERVERS= can be removed as you reset the variable in the following line, and I would not use a pluralized variable for a single item. One last thing, printing out the name of the server you are connecting to can make things much clearer as well. Here's a quick rewrite.

Code:

#!/bin/bash
for SERVER in $(cat servers)
do
    echo $SERVER
    ssh MyUserName@$SERVER df -h
done
