in thread Array searching, grep, first

There are usually 90-120 lines in the CSV per day, so I'm not sure it matters.

Can I get a little explaination on whats going on with grep { $csvlist[$_] =~ /$x/} 0..$#csvlist; it looks like it would be useful.

    What's going on here is that the list that is being greped consists of the numbers 0..$#csvlist. (Or zero through the highest index in the array.) The conditional inside the grep block looks at the array item indexed at each number and returns that number if the condition is true.
