[SOLVED] Code to ensure script runner is root user

mogleyzw · 05-27-2012, 06:34 AM

Hi,

I just need a code fragment with checks if the user is the root user.

Basically I need to ensure it was run as "sudo myscript" rather then just "myscript"

I found

Code:

if [ "$USER" != "root" ]; then 
    echo "You are not root user, please log in as root user"
    exit
fi

But that didn't work. I thought maybe it was because I had not defined the variable $USER and I wasn't sure how to.

Any help will be appreciated.

You can use "id" program, like that:

Code:

if [ $(id -ur) != 0 ]; then 
    echo "You are not root user, please log in as root user"
    exit
fi

Why not just set the execute permissions so that only root can run the script?
