Re^5: Delete files if they match help!

I wouldn't bother with -e and -f, I'd go straight to -f. Also, if you're going to delete the original, then why copy it to the new location? Why not just rename the file into the new location and do it all at once? Finally, rather than jumping through hoops with map to get the values from the hash, I'd just get them directly. With those changes, it comes out to something like this:

...
my $dir_to_open = "../../pics";
my $dir_to = "../../back";
while (my $row = $sth->fetchrow_hashref()) {
    for my $imgfile (values %$row) {
        if (-f "$dir_to_open/$imgfile") {
            rename "$dir_to_open/$imgfile", "$dir_to/$imgfile";
        }
    }
}

why copy it to the new location? Why not just rename the file into the new location and do it all at once? The move (from File::Copy) which the OP was using is essentially a rename that also works across file system boundaries. With source and destination being on the same file system, it simply does a `rename` under the hood. With different file systems, it copies the file to the destination and deletes the source. In other words, it's more flexible in case this should be required. Otherwise, it's the same anyway, i.e. a `rename`.	[reply] [d/l] [select]

You are right, I should do this way no "jumping through hoops". Thanks for your feedback!	[reply]
