Can't you use the grep solution of sunpraveen with perl?

Old 09-09-2009
Perl grep require regular expression.
I think "grep -v" option given by sunpraveen will work only on shell.
I am using php function like preg_grep("/^(10.10.10.*)/",$ip_array).
So it requires pure regular explression.

I hope someone who's familiar with perl can give you the solution since I'm not familiar with it.
