What does Drop root mean in Linux

Solution 1:

It simply means that you should start the application using root privileges and then afterwards, don't use root privileges for any other commands.

If you are using sudo to launch the application, you can run the following to "drop" the root privileges:

sudo -k

This will revoke the user's cached credentials. So the next time you try to run a command with sudo, you will have to enter your password.
