Shell Scripting, Needing someone to teach me some stuff.

[Citrix]

Hey guys

I am busy creating a script for my community servers, the issue i am having is that i think i am doing stuff the long way. Also know that since Counter-Strike: Source has changed there file structure it makes thinks a lot harder.

We have 4 types of servers.

Counter-Strike: Source
Team Fortress 2
Left 4 Dead 2
Minecraft

I am needing some help make a management script for the dedibox.

Also can people mark out places where i can improve it. Also please state how i can do that.
Also if you do want to help me. you can contact me on steam if you like.
