With this command, you should see the list of all the files and directories on your current location. It’s simply a list command with a -l switch. To view the file permissions of the files inside your current directory, enter the command ls -l.

Now that we’re familiar with superuser and how to access it via su and sudo, let’s move on to the file level. Once authenticated, you can enjoy the target user’s privileges without having to enter the command again in every action.
But instead of asking for the specified user’s password, it asks for yours. Just like su, it prompts you with a password for authentication. On the other hand, you can use sudo or “super user do” to perform actions as the root user. Then, to exit the shell, simply enter exit on the terminal. Once logged in, you enter a temporary shell with that user’s privileges.
Please take note that to change to the specified user, you need to enter their password first. Additionally, you can include a - before entering the username to take the user settings and the privileges. If used without a specified username, su assumes root user. Su and Sudoįirstly, the su command stands for “substitute user.” When executed, it lets you do things in the command line with the privileges of another user. The best way to do this is to gain root user access through the su and sudo commands. However, at times, you’ll need to change something that affects the whole computer. The account privileges of pi are usually enough to work with basic tasks. On the Raspberry Pi OS, you are logged in as a user named “pi” by default. It’s called the root user or the superuser. You can create many users on a Linux system, but there will always be a special user that has administrative access to all files and directories. In this article, we will see how to set those permissions on files using a Raspberry Pi.
