Of course you can also access mysql from the command line - pretty simple to do, but depending on how your server is configured and what access your user account has you may have to do it differently
Basically..
First log into mysql
Type mysql at the commend prompt - it should then ask you for your username and password. This should log you in to mysql. You can also specify this as one command -
mysql -u user -p password
Now depending on what permissions you have been granted - you may be able to simply run mysql statements straight away - this may be true if you only have been granted access to one database, if you have other priviledges, you may need to explicitly select your database or include it within your sql
I'm glossing over this - as it's been a while, but it really isn't too hard - best thing is to Google for a command cheat sheet or simply type help once you are logged in
