Subject description: runs command as non-priviledged user		  
Hi folks!

Some apps are just not safe to be run as root - particularly my browser and my server - so I've decided that i don't want them to. In order to do so comfortably, I've created a script that lowers the privileges ( an anti-sudo, perhaps ) Very Happy

So, here it is:

Code:
#!/bin/bash
if [[ -n $@ ]]; then
        # allows gtk to run
        xhost local:lower@ > /dev/null
        sudo -H -u lower $@
else
        su lower
fi


In order for it to work, you need sudo, which I attach below. Created using this guy's code ( thanks! ). Also, you need to create the "lower" user, which can be done with

Code:
adduser lower


Usage:

Firstly, you need to create a text file in "/usr/bin" called "lower". Insert the first block of code of this post inside that file, and give it execution rights ( tip: `chmod +x /usr/bin/lower`)

After that, you can use it like this

Code:
#lower firefox


or

Code:
#lower
#firefox

( you can use "exit" command to become root again )
