I wrote this function...the concept is simple but hey I am a perl newbie, so it doesn't really work as intended. The function is supposed to be passed a path name, check to see if the file exists, and pipe the output from a cat function (of that file) to a new file (which is saved into a predetermined directory). Now, here is my broken function: 

sub find_files {
    my $file_name = shift;
    my $path = qx/pwd/;
    print $path;

    my $file = basename($file_name);

    open(my $FILE_H, '>', "$path/$file"); #||                         
+                                                                     
+                                          
          #  die "Unable to open file: $!";                           
+                                                                     
+                                          

    if(defined(qx/test -e $file_name; echo $?/)) {

        my $file_data = qx/cat $file_name/;
        print $FILE_H $file_data;
    } else {
        print "here";
        print $FILE_H "Unable to find file name: $file_name";
    }
    close($FILE_H);
}
