in thread using File::Find for reading files in order

In the find sub, $_ is equivalent to File::Find::name
Nope. $_ holds the name relative to the current directory at the time of the subroutine call, which in the default case has been chdir'ed to the location of the file. But $File::Find::name is always relative to the original directory.

So they aren't the same. Definitely different uses. You can use $_ inside the subroutine, but if you want to save the name for later, you want to use $File::Find::name. And in fact, it'd be wrong to use $File::Find::name within the subroutine, because your relative name would have been applied twice. Ouch.

    merlyn, Thanks for clarifying. I was hesitant to say "equivalent"; even to say anything other than "you can shorten your code..." And now I've reread the doc, a Good Thing.

    I've reread the OP too, and I think the claimed output is misleading. Surely it is more like the following? (In which case my suggestion can be stricken, as it would only yield the files.)

    /path/to/File 1 /path/to/File 10 /path/to/File 100 /path/to/File 2 /path/to/File 20 ...

    Whew.
