Periods in run-parts

Repeat after me, Debian/Ubuntu sysadmins. You cannot use the period (.) character in /etc/foo.d directories. Can't can't can't.

Why? Well, man runparts says:

If the --lsbsysinit option is not given then the names must consist
entirely of upper and lower case letters, digits, underscores, and

So, you can't have files named "" in your /etc/logrotate.d directory, and you can't have files named "" in your /etc/cron.d directory.

As much of a big deal is made of Halloween, and as many groups of kids I saw walking the streets about 7:45, we only had one person knock on the door trick-or-treating. And we managed to successfully pretend we weren't here, sitting in the lounge watching Torchwood. (I keep waiting for the Doctor to turn up.)

    Next best thing... next week is a Cybermen tie-in! 🙂

    Hmmm, yes, well. It seemed they were looking for ways to slot "old Doctor Who" things into "new Doctor Who" episodes. This feels just like that, but more contrived. 🙂

    Force of habit makes me add ".sh" or ".pl" or ".py" to the end of scripts when I write them, and cron doesn't give you any feedback about files that have been skipped (hey, it would be user-friendly to print something about skipped filenames to syslog). The cron manpage at least seems to mention it nowadays, but I'm sure when I looked into this in the past the manpage just mentioned "run-parts" in brief, so it would have to occur to you to read that manpage as well to see why your cron scripts aren't working.

    This is completely non-obvious unintuitive behaviour, even by unix command-line standards, and I think it should be changed to how the the majority of users expect it to behave. (Other distros don't have this restriction - run-parts was originally written by Debian.)

    See 350242, 308911, 324922 and 243676 among others, I'm sure.

    "Can't change it, it'll break 10 years of old stuff". "Submit documentation patches please."

    The best answer is have it e-mail you things it silently avoided.
