Facron 0.9 released

by Marc-Antoine Perennou on December 7, 2012

Tagged as: facron, fanotify, cron, sysadmin.

Usually, every Thursday I publish another post in my “Knowing your system” saga, but this week I was busy working on facron. I plan to publish the part three on next Monday, it will be about source-based GNU/Linux distributions.

What’s in this release?

Since last time I wrote about it, a few things have changed: the code is more robust and much cleaner, and several improvements have been made:

  • You’re now able to pass arguments containing spaces if you surround them with quotes or double quotes in the configuration file.
  • The fanotify flags handling have slightly changed with a new separator, the comma. If you specify FAN_MODIFY|FAN_CLOSE_WRITE,FAN_OPEN the event caught will be: either FAN_MODIFY AND FAN_CLOSE_WRITE, or FAN_OPEN.
  • $@ is now the dirname of the file, $# the basename ($$ is still the full path)
  • A manual is now provided
  • A systemd service is now provided (supporting the reload action to reload the configuration)
  • You can now pass the --background argument to facron to launch it in background on non-systemd systems.

How do I get it?

The release tarball is available there: https://github.com/Keruspe/facron/downloads.

You must have fanotify included in your kernel (most recent systems should have it by default).

Here are the steps you need to run in order to get it up and running:

Then just create your configuration file as I said in the previous post or following the manual instructions (man facron).

When everything is ready, you just have to run

Or for non-systemd systems

If you edit the configuration file, you can reload it without restarting the daemon by running

Or for non-systemd systems

I hope you’ll enjoy it. Feel free to propose new features and/or to contribute!
