RE: [PHP] trouble with telnet.

Actually there's a nice bash command: $ which mysql that is supposed to show you the folder where binary is... I mean my understanding is if there's 'mysql' binary that means mysql is installed. alternatively you can do this also: $ find / mysql* // what this one will do is it will start looking for mysql on your filesystem and give you results at the end Hope this was helpful Vlad p.s. I think the commands Andrey pointed out work also
