dear monks. I have a file in which I am getting the input from. I wish to generate output files and store these output files in different folders. as in out1.txt should be stored in directory1 and out2.txt needs to be stored in directory2 and so on. Using the current code I am able to create all possible combinations of the values present in my input code and put them in different files. My input file looks like

 
Delhi Beijing Canberra NewYork
hot cold rainy
go dontgo cannotcomment
[download]

One sample output file will look like

City : Delhi
Weather : hot
recommended : go
[download]

another will look like

 City : Delhi
Weather : hot
recommended : dontgo
[download]

I want to print all possible combinations of the of city, weather and recommended , and the code below does that. But I also want to take each output file and put it in a different folder. Which is where I am having the issue. I think I should use the makepath keyword and use it inside the loop. But once I use the use File::Path, it gives the error :

 syntax error at perl_script.pl line 8, near ")
    or"

Line 8 just opens the file for input. This is why I am confused. Could you please help let me know how I can modify the code to put the files in different folders?

 #! perl -slw
use strict;
use Data::Dumper;
#use File::Path

open(my $in, '<', 'ocean_dummy')
    or die "Cannot open input.txt: $!";

my @city = split ' ', <$in>;
my @temp = split ' ', <$in>;
my @note = split ' ', <$in>;

#perl -MFile::Path -e 'mkpath([map { "dir$_" } (1 .. 20)])'
#-e 'mkpath([map { "dir$_" } (1 .. 20)])'
#mkpath([map { "dir$_" } (1 .. 20)]);

my $i = '01';
for my $city ( @city ) {
    for my $temp ( @temp ) {
        for my $note ( @note ) {
        #mkdir directory_$city$temp$note
            open O, '>', 'out' .  $i++ or die $!;
            print O 'city: ', $city;
            print O 'weather: ', $temp;
            print O 'recommended: ', $note;
            close O;
        }
    }
}
