All,
I have an array whereby each element in that array is of the following format:
@myNames = ('a b', 'c d', 'e f', 'g h', 'i j');However, I am only interested in grepping the second part of each element - i.e. b, d, f, h and j.
How do I grep for second part? Would Map be helpful?
I get the entire element returned and not the section of that element that I am after.

Grep is a boolean test. Does it match? If so, we want it.
If you are modifying the data, map works better.
my @lastNames = map {(split / /)[1]} @myNames;This is useful. Try already mentioned Perl Grep function.
