SSH to server, Sudo su - then run commands in bash

Ben Coughlan picture Ben Coughlan · Apr 2, 2014 · Viewed 28.2k times · Source

I have the following

#!/bin/bash

USER='scott'
PASS='tiger'

ssh -t [email protected] "sudo su - http" 

This Works, but I was trying to get it to run a script afterwards, and if I do, using -c or <

The script does a grep like this:

grep -i "Exception:" /opt/local/server/logs/exceptions.log | grep -e "|*-*-*:*:*,*|" | tail -1 | awk -F'|' '{print $2}' >> log.log

This also works fine on it's own, but I need to be http to do it.

I cannot SCP the output of the script back to server001 either, so I'm stuck here,

Any ideas would be relay appreciated. Ben

Try

ssh -t [email protected] 'sudo -u http grep -i "Exception:" /opt/local/server/logs/exceptions.log | grep -e "|*-*-*:*:*,*|" | tail -1 | awk -F"|" "{print $2}" >> log.log'

Sudo already runs the command as a different user to there's no need to su again.

Only reason to do sudo su is to have a fast way to start a new shell with another user.
