Passing options to a bash script

I'm just not sure where to start looking into this. I want to be able to create switches for my script. Back in the day I'd make my scripts interactive...you know:

Code:

echo "what report do you want"
echo "A)boxes with errors"
echo "B)boxes with more than 5 errors"
echo "C)Service groups that have thrown errors"
read $1
if ...

but now that seems kind of amateurish. I'd rather have a script where errorreport.sh -c made a list of boxes, errorreport.sh -m listed boxes with multiple errors and so on.

I'm not asking anyone to give me a step by step on how to do this, I'd rather learn by doing, but I don't even know where to start. I've tried googling "adding switches to bash scripts" and the like, and I've been scanning my o'reiley books, but at quick glance I don't see what I'm looking for.

If anyone could tell me where I might at least start reading up on this I'd appreciate it.
