Re^2: Optimizing performance for script to traverse on filesystem

[gdanenb]

If I use

while ( my $name = readdir( DIR )) {
    ...
}

I have to leave DIR opened while walking deeper in recursive
Only when all directories on the level are scaned, I can closedir(DIR)
Isn't it problematic ?

Is the structure likely to be more than a few tens of directories deep? If not, no problem. If it is then you'll have to work really hard to fix the problem regardless of what tools you use because most simple solutions will keep directory handles open.
