Hello good people,

I am trying to understand Perl and why things work. Could someone break
down for me the snippet of code below and tell me exactly how the
operation works. I guess I am mostly confused about the placement/order
of elements of the code and how Perl interprets it. Oh and exactly how
does $_ work. I think if I could get a better understanding of the how
and why it might clear up my confusion. Thanks, Patrick

(grep {$newfile eq $_} @files)
