edit: Added teddy bear, removed foot from mouth

That would also work, but I think it would risk using more memory than loading the first file into an array, since you'd risk loading hash elements upon which you will not be reporting.

However, because it's you, I naturally presume you have a reason for using that approach, and I'm concerned that I can't see why.

So I guess I'll bite the bullet and ask -- Why do you recommend loading the ticker info to hash first?

However, I just asked my teddy bear and the answer came back clearly: My way trades away execution efficiency to gain space efficiency. That is silly given the OP specifically stated there would only be a few thousand lines. The linear search via grepfor every line of the ticker file is a complete waste.

I'll go and hide in my corner now.
