Watcher is a daemon that watches specified files/folders for changes and fires commands in response to those changes. It is similar to incron, however, configuration uses a simpler to read ini file instead of a plain text file. Unlike incron it can also recursively monitor directories.
It's written in Python, making it easier to hack.
This fork is a rewritting of the code using python-daemon implementation of PEP3143
You need Python 2.7 and the following modules that can be installed with pip:
To install pip on Ubuntu:
sudo apt-get install pip
To install the modules:
sudo pip install python-daemon lockfile pyinotify
For Python 3, install python-daemon-3K instead of python-daemon:
sudo pip install python-daemon-3K lockfile pyinotify
See the provided watcher.ini file for an example job configuration. The
config file should reside in /etc/watcher.ini or ~/.watcher.ini. You
can also specify the path to the config file as a command line parameter
using the --config option.
If you edit the ini file you must restart the daemon for it to reload the configuration.
Make sure watcher.py is marked as executable:
chmod +x watcher.py
Start the daemon with:
./watcher.py start
Stop it with:
./watcher.py stop
Restart it with:
./watcher.py restart
If you don't want the daemon to fork to the background, start it with
./watcher.py debug
