$ means you're giving Linux commands as a regular user #

means you re giving commands as the Root user

On any Linux computer, there are regular users and the Root user Giving the su command allows you to give commands as

the “Super User,” or Root user, of the computer

As the Root user, you can add/delete/modify any file on the

computer A regular user can’t do this

The Root user has the power to really mess up the computer, so you should only work as the Root user when necessary

Here’s what this string of commands means:

e mysql

mysql -u root mysql

This first mysql starts the MySQL client

MySQL is made up of two parts: the MySQL server program and a MySQL client program

The MySQL server program handles the storage of the data The MySQL client program allows you to give commands to the MySQL server

You need both parts to make MySQL work

e@ -u root

mysql -u root mysql

The -u command tells the MySQL client that you want to log into the MySQL server as a particular user root denotes the root user of the MySQL server

Youre not logging into the Linux computer as the Root user; you're logging into the MySQL server as its root user This gives you total control over the MySQL server
