Every Linux user has to use the root login from time to time.There are some things that cannot be done on the Linux system without logging in as root. However,use of root login in regular use is not advisable and should be avoided.This is because the root login does not restrict anything that you want to do. With as simple command issued by accident, it could render the Linux system useless as well as ignite the loss of that that are critically important. Hence, experimenting with the commands should be avoided when logged in as root user.
Instead use 'su root' or 'sudo' or 'su -c' depending on your system to accomplish certain tasks without re-logging into Linux system.
With great power comes great responsibilities.
