Shell Programming and Scripting

I am writting a script in csh and I am blanking out on how I code in the ability to process user input in the middle of a while/end loop.

while(1)
args..
end

it is a simple script, and I want to add hotkey functions, like q to quit, z to zero counters, etc..

Google has not been very friendly on this matter.

I hope that someone could give me a push in the right direction, clue my in to what command(s) i should be using.

thanks,

nevermind this post. im going to do this via C, scripting is just too cumbersome for all of the tasks im going to need this to do.


so... does anyone know where i can find a good unix C manual online?
