Thanks! I think I've got most everything updated. That input-output redirect is especially good to know.
I left the F.first and F.last because I think they're a bit easier to read, and it's possibly a bit more idiomatic Ruby to use methods when they're available (like using item.zero? instead of item == 0). If you wanted the second item, $F[1] would be fair though.
Anyways, thanks for helping me make my post better, I really appreciate it!

Good one, liked the way concepts are introduced :)
Some note points:
1)
$_is default for regex match (also note the missing dot)2) Don't redirect output to same file as input, you'll be left with empty file
See bash pit fall , stackoverflow, unix.stackexchange etc
3) As shown in last but one example,
$_.gsub!can be shortened togsub4) Can also use indexing to get first/last element of array, i.e
$F[0]and$F[-1]respectivelyThanks! I think I've got most everything updated. That input-output redirect is especially good to know.
