Question

which Linux command can be executed by a logged in user in order to change to root user

​

Answer 1

Answer:

Sudo stands for SuperUser DO and is used to access restricted files and operations. By default, Linux restricts access to certain parts of the system preventing sensitive files from being compromised.

The sudo command temporarily elevates privileges allowing users to complete sensitive tasks without logging in as the root user.

sudo was developed as a way to temporarily grant a user administrative rights. To make it work, use sudo before a restricted command. The system will prompt for your password. Once provided, the system runs the command.

When the sudo command is used, a timestamp is entered in the system logs. The user can run commands with elevated privileges for a short time (default 15 minutes). If a non-sudo user tries to use the sudo command, it is logged as a security event.

Answer 2

sudo command

Linux command can be executed by a logged in user in order to change to root user .

• You can run programmes with another user's security rights by using the sudo command (by default, as the superuser). It requests your unique password and verifies your intent to perform a command by consulting a sudoers file that the system administrator has set up.
• The sudo package comes pre-installed in the majority of Linux variants. Let's just write sudo and press enter to utilise it. The sudo package usage information will be shown if sudo has been installed. A "command not found" notice will appear if it isn't.
• You can run applications as a different user, by default the root user, using the sudo command. Sudo is one of the commands that you will use frequently if you spend a lot of time on the command line.
• These users must have an entry in the "/etc/sudoers" file to be able to use the sudo command. Keep in mind that you must use the sudo command to see or edit the sudoers file. It is advised to use the "visudo" command to edit the sudoers file.
