basarix has asked for the wisdom of the Perl Monks concerning the following question:

I am making my first steps in perl, and i am faced with a lil problem. i need to work with files and dirs, but restricting the files i have to work with. therefore, i used the find2perl utility to make myself a nice perl code that would give me the files i am looking for, but in order to work with them, i need to get them into an array, so i can process them. i am not finding a way to put the results of the find search into an array. I know this is probably something very easy to solve, but i am hopelessly stuck, and need to get it solved soon..... thanx noble monks for your wisdom on this... THanx all, i have solved this issue.... u've all been a good source of help / ideas

    I'm no File::Find expert, by any means, but this works for me:

    ... my @list_of_files; File::Find::find( \&add_to_list, $path ); sub add_to_list { push @list_of_files, $File::Find::name if ( /#some criteria# /); } ...
    It's sad that a family can be torn apart by such a such a simple thing as a pack of wild dogs
      Thanx.... i will try it asap....

    File::Find::Rule returns a list of files and uses matching criteria similar to the find command.


    #!/usr/bin/perl use strict; use File::Find::Rule; use Data::Dumper; my @list = File::Find::Rule->file()->maxdepth(1)->in('.'); print Dumper \@list;

    File::Finder has a gather() method that will work for you, or you can look at some of the examples in File::Find::Closures. I try to stay away from global (or file-scoped lexicals) in these sorts of problems.

    Here is my find example. I use this when I need to remember how to use find. Course I didn't know about File::Find::Rule! Good to know.
