Wow brilliant response from all of you. Really appreciate the feedback. There's a hell of a lot of it lol! But it makes me see the point raised that if I ever need guidance, I can turn to you guys. I'm one of those people who likes theory then to apply. Something I'm working on but I think in this context it makes sense.
Hoping to be able to work with Linux more in the future, not only to solve PC problems but, if all goes well with my Uni applications, use what I've learnt to use Linux to create economic modeling programs or such. Long way off, seems that the language "R" is used for that sorta thing. Saw it on wikibooks/wikipedia. Did also mention licences can be around 200,000 for those products. Tasty.
@mynis01 and rhowaldt
Bash seems a sensible place to start. Terminal is intimidating but by the looks of the tutorials should clear things up quickly 
@Awweb
...What?
One day maybe it'll be clear what I'm looking at.
@mynis01
sed seems really cool
Definitely will move onto it after I get to grips with Bash and C (easier than it sounds I guess).
@.not
Life lesson there, something I'm trying to apply
but we all know, Rome wasn't built in a day 
@kowloonboy
Python's on the list too, eventually get there lol.
Thanks again
