in reply to create hash using grep
Hi Luca,
You should consider the fact that 'grep' creates a temporary data structure and that Perl's garbage collection probably won't release it back to the OS (from my experience).
Please consider a simpler way to do what you ask without consuming exessive memory -
Note that you can use the same loop for adding more restrictions or perform more actions if you need, which may save you run-time in some cases.foreach (keys %$a){ !/le/ and $c->{$_} = $a->{$_}; }
Enjoy,
Mickey
