in reply to Return a Unique Array

GrassHopper! Always read the books. In the Perl Cookbook you can find

my %seen =() ;
@unique_array = grep { ! $seen{$_}++ } @non_unique_array ;

Which makes the soul happier!

[choroba]: Lady_Aleena Perl's grep is not related to directories
[Your Mother]: It does recurse.
[Lady_Aleena]: choroba, I know.
[Your Mother]: -R, -r, --recursive
[1nickt]: Discipulus, Corion, try this: D.A. Golden's blog
[Lady_Aleena]: Your Mother, that's the command line grep, not perl's grep.
[Your Mother]: …how on Earth could Perl’s grep recurse?
[Tanktalus]: perldigious: I'm not looking to get rich. I'm looking for interesting work, with good continuity of employment, and maintenance of our current lifestyle. (An improvement wouldn't be bad, either, but that's not a requirement ;) )
erix enjoys the confusion++
[Your Mother]: :P
