Connecting to a MySQL database from the command prompt can be very easy:

[root@mypc]#mysql -S /opt/db/mysql//mysql.sock -uroot -prootPassword

Here, we are trying to connect to the MySQL database

1. Installed in location /opt/db/
2. Database Name is the database name
3. -u indicates the parameter username, i.e. in this case it is root
4. -p indicates the parameter password, in this case it is rootPassword

Most importantly, we are connecting using sockets, which is faster than any other type of connection.
