Perl LWP::Simple::getstore How to check if the file exists in destination directory

Question

In my Perl script I am using LWP::Simple::getstore to retrieve an image and store as file. But before storing how to check if that file already exists?

this is the snippet

use constant FILE_DIR => "/home/destination/files/";
my $image_path = FILE_FOLDER."$item_id"."_"."$file_date.$image";
my $res = LWP::Simple::getstore($image_url,$image_path); 

Please help me with this.

Thanks

You can use a file test , eg

unless (-e $image_path) {
    LWP::Simple::getstore($image_url, $image_path); 
}
