For all of that, I use a custom little shell framework and some scripts that I share with all my servers through my own git repository.

I decided to publish theses files : it might be useful for some one ;).  The “framework” and configuration variables are in whereas scripts are in

What the framework provides


Basicaly, the framework has the following features :

  • Redirect all output to a formated log file (eg: prefix added to every line)
  • Log file send to admin
  • Error manager (auto umounts, send mail, etc.)
  • Provides base functionalities such as directory sync, log writing, mysql backup, directory backup, changes detection in directory, etc.

Output example

The framework allows me to write small scripts that output log file like the following (for instance, a backup script):


Example scripts
