Use sudo command for script SSH server

Question

I have to do following steps on several servers:

1. log in with my username
2. type in sudo su -
3. type in amCLI -l 32/1 | grep Firmware

So I would like to write this all in one script, my idea was:

#!bin/bash
for hostname in DPM-BZ0201 DPM-BZ0202
do
ssh -n vneudeck@$hostname "sudo su-; amCLI -l 32/1 | grep Firmware"
done

or

#!bin/bash
for hostname in DPM-BZ0201 DPM-BZ0202
do
ssh -n vneudeck@$hostname "sudo amCLI -l 32/1 | grep Firmware"
done

Both don't work though.

Answer 1

A better solution is to set up sudo so that your user is allowed to execute /full/path/to/amCLI without providing a password.

Then you can simply

#!bin/bash
for hostname in DPM-BZ0201 DPM-BZ0202
do
    ssh -n vneudeck@$hostname sudo /full/path/to/amCLI -l 32/1 | grep Firmware
done

Answer 2

Maybe if you put vneudeck@$hostname in double quotation, it will help. And there is no space between su and - I hope it is helpfull

Answer 3

The first one won't work:

sudo su -; amCLI -l 32/1 | grep Firmware

This would execute sudo su -, and when this returned (i.e. when you were done processing commands as root and exited) it would execute amCLI. (Note also that an alternative to sudo su is sudo -s, though sudo su - does more I think.)

The second version might work with some conditions: sudo should not be asking for a password, and amCLI should be in PATH (not root's path, which is probably set when you type sudo su -, but your path, because sudo uses your path). Try specifying the full path to amCLI, such as /usr/local/sbin/amCLI or whatever it is.
