in thread glob() and dot files

You are correct.
my @files = glob('*'); # current directory print "",join("\n",@files), "\n";
# Note that these file names do not say whether or not they are directories, a file test is needed. I demo'ed this at Re: Getting a list of directories matching a pattern.

Update: I experimented with Windows 10 command line and found that I could indeed create a directory with a "dot suffix". That surprised me.Having said that, I have never seen such a thing in "real life". By convention, that is just not "the way that this is done". A long time ago, I was forced to use readdir and grep to get file names because of incompatible glob's. For production code, I still use readdir and grep because it will always work. For quick hacks, I am fine with glob().

    The two places I see it happen the most are when some programs put their version number as part of the directory name (C:\Program Files\FooBar v1.23) or when *NIX tools are ported to Windows.

      Good comments.
      Instead of something like: C:\Program Files\FooBar v1.23, I use personally would use: C:\Program Files\FooBar v1_23. However not all folks think that way. True.

      Having said that, I am a supporter of using readdir(). Having been burned a few times with different versions of glob(), I use readdir() for all production code. I do sometimes use glob() for short tests where my code is just looking in the current dir for specific ".suffixes".
