Require sudo in bash script
Use the following code snippet in bash scripts that require root privileges to prompt the user to become root using sudo.
if [ "$EUID" -ne 0 ]; then echo "This script requires root." sudo su -s "$0" exit fi
If you need to pass arguments to the script, you will need to tweak the
sudo line a little bit such as:
sudo su -s "$0" root $1 $2
