    Depeding on how long you intend to spend doing stuff in each directory, it might be a good idea to do a chdir into that directory. This would avoid running into problems like the one you just had.

    This is one of those philosofical issues, like what's best:
    • relative links
    • absolute urls
    Each person has a particular way of doing things, but I just tend to think its a matter of what makes things clearer. In your case, it could be:
    if (-f "$path/$leaf") { } # or simply chdir($path) || warn(); if (-d $leaf) { }

[Corion]: Meh. I'm now on Firefox 57 ("Quantum") and again have to remove Pocket, and reinstall the adblocker, uMatrix (because NoScript doesn't work) and silence the about:blank page to not download crap from the internet
[Corion]: Maybe I shouldn't update software ...
[ambrus]: Corion: my guess is to first read the start of the file to check what format it is out of two or more possibilities, then rewind it and handle it differently depending on the program
[ambrus]: s/program/format/
[Dumu]: ambrus: it's about testing a file for being multiple possible file formats
[ambrus]: In particular, you might want to detect the encoding of a HTML file from between utf-16 versus ascii-based and encoding given in a META tag.
[ambrus]: Dumu: it should probably be safe to change the encoding if you rewind first with seek $file, 0, 0 first
[Dumu]: ambrus: good guess. I'm trying to contribute to a CPAN module, and the existing tests assume they're looking at text files
[Dumu]: ambrus: thank you. I was seeking afterwards. I'll seek first.
[jedikaiti]: Hello, Dumu!
