grep doesn't give back portions. you seem to misunderstand what grep
does. it only returns some of the elements in its input list. it is a
filter.

use grabbing as in most regexes. don't compare perl to awk as perl is a
full programming language vs awk's whatever you call it (and i used awk
a ton before i got into perl!).

don't use grep then. or use map and then grab the parts you want. map
has a similar syntax to grep but instead of filtering, it builds a new
list from its expression/code block. you can grab the part you want in
the regex and map will return it in a list.
