That's very odd. On my Leopard OSX box, "grep" works exactly as I would expect (that is, "-i" causes it to ignore case).

I don't use Firefox so I can't check, but I would suspect that the "F" in...

The sed expression above is missing a forward-slash.

Or wait, no it's not. That DOES look right! Weird, nevermind. Maybe this version of sed uses "$1" instead of "\1"??

The output from "wc" usually has some embedded whitespace, which can prevent the shell from treating it like a number:

The "tail" command is not a shell builtin, so the shell should have no impact.
