Have you ever come across commands like 'sudo' and 'su' on your Linux system and wondered what they are used for? If so, you've come to the right place. In this article, we'll be exploring the difference between these two important commands.

Sudo and su are both commands used to gain elevated privileges on a Linux system. However, they differ in their functionality and the way they work.

Sudo, which stands for 'superuser do', is used to execute commands as a superuser or root user. This means that when you run a command with sudo, you're essentially elevating your user privileges to those of the root user. This is important because many system-level tasks require root-level privileges to execute. By default, sudo requires a password before it can be used, providing an extra level of security.

Su, on the other hand, stands for 'switch user' or 'substitute user' and is used to switch to another user account without logging out. This command doesn't necessarily grant root-level privileges, but it allows you to execute commands as another user. By default, su doesn't require a password and can be used by anyone with access to the system.

So, why would you use one over the other?

As mentioned earlier, sudo is used to execute commands with root-level privileges, whereas su is used to switch to another user account. If you want to execute a command with root-level privileges, you should use sudo. If you want to switch to another user account to execute commands, you should use su.

It's important to note that both sudo and su can be used to elevate your privileges to the root user, but the way they do it differs. Sudo executes a single command with root privileges while su sets up a new shell with root privileges. This means that when you use su, you're essentially creating a new session with root privileges, which can be a security risk if not used carefully.

In conclusion, sudo and su are two important commands that are used to gain elevated privileges on a Linux system. While both commands serve a similar purpose, they differ in their functionality and the way they work. It's important to understand their differences and use them carefully to avoid security risks.
