To perform administrator tasks on Linux, you must have root access (superuser or superuser). Having a separate root account is common on most Linux distros, but Ubuntu disables superuser permissions by default. This is to prevent you from accidentally making errors and keep your system safe from suspicious intruders. To execute a command that requires root access, use sudo .
Steps
Execute root with sudo . command

- For example, the sudo /etc/init.d/networking stop command will stop the network service, while the sudo adduser command will add a new user to the system. These tasks all require super user permissions.
- You will be asked for your password before sudo executes the command. Linux will save your password for 15 minutes, so you don’t have to enter it again and again.

- For example, you can type gksudo gedit /etc/fstab to open the file “fstab” with the Gedit editor in the GUI.
- If you use KDE Window Manager, use kdesudo instead of gksudo .

- Enter the command sudo passwd root to create a root password, which essentially “activates” the account. Do not forget this password.
- Type sudo -i . Then enter the root password when prompted.
- The command line interpreter will change from $ to # , which means you already have root access.

sudo
or gksudo
instead. If you absolutely must have a separate root account (as is the case with a request from some program your business uses, or this dedicated computer is only used by a single user), you can activate the super user account with some simple commands.
- Ubuntu does not recommend activating the super user account because this can bring risks to the system. [5] XResearch Sources

- To disable the super user account, enter the command sudo passwd -dl root . [7] XResearch Sources
Advice
- You should minimize logging in as a super user. You can execute most commands that require root privileges with sudo or gksudo .
- You can also use sudo –i to access other users’ shells on the system. For example, to become “tao”, you would type sudo –I tay and enter YOUR password (not that of “tao”) when prompted.

In conclusion, gaining root access on a Ubuntu system is a powerful capability that allows users to have complete control over the operating system. However, it should be used with caution and only by experienced individuals who understand the risks and responsibilities that come with it.
The process of obtaining root access involves either enabling the root account or using the sudo command. Enabling the root account requires setting a password for the root user, whereas utilizing sudo grants temporary administrative privileges to regular users.
It is essential to remember the importance of security while dealing with root access. Regularly updating the system, using strong passwords, and restricting physical access are some of the precautions that should be taken to prevent unauthorized access.
Moreover, it is crucial to utilize root access responsibly and only perform tasks that are necessary and justified. Unintentional modifications or deletions at the root level can have severe consequences on the stability and security of the system.
Overall, gaining root access on Ubuntu can be a valuable tool for system administrators, developers, and advanced users. Nevertheless, it should be treated with the utmost care, understanding the potential risks and acting responsibly to maintain the integrity and security of the operating system.
