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

Question

This question already has answers here:

Pass commands as input to another command (su, ssh, sh, etc) (3 answers)

I have the following

#!/bin/bash

USER='scott'
PASS='tiger'

ssh -t $USER@server006.web.com "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

Answer 1

Try

ssh -t $USER@server006.web.com '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.

Answer 2

You probably want sudo -u instead of sudo su -:

ssh -t $USER@server006.web.com sudo -u http script 

Answer 3

Guess I'm late to the party. My solution:

ssh -t $USER@server006.web.com "sudo cat /etc/shadow"

and replace cat /etc/shadow with your desired program.
