Jobs that involve computer cmd commands?

Heya,

I'm a guy who loves computers,

and who also aspires to have a job who is heavily involved in computers aswell.

I just wanna' know if there's a job out there that involves me using CMD commands, and maybe security from hacking etc,

So I can one of them important IT guys in security and all that.

Would prefer to pay quite a bit (Who doesn't want this? :P)

I don't mind that it's hard, just tell me something that I can work to,

Many thanks,
