Syncd is a simple bash script that watches for file changes and rsyncs them to an other folder. It uses inotify to watch for file system changes and syncs the whole directory. The script makes sure to aggregate change events during a running rsync, such that after the initial sync a subsequent sync can be triggered (and so on).

Right now a linux based system with inotify-tools and rsync installed is required, .e.g for ubuntu/debian based systems run

apt-get install inotify-tools rsync

For Mac OS X support https://github.com/ggreer/fsevents-tools could be integrated instead of inotify.

• Clone the script in a directory of your choice, e.g.

cd ~/opt
git clone [email protected]:drunomics/syncd.git

• Best, put syncd in your $PATH, for example by running:

cd syncd
sudo ln -s $PWD/syncd /usr/local/bin/syncd

• Copy the syncd.conf file to the directory you want to sync, or in some of its parent directories and adapt it your needs.
• Run "syncd start" in any directory below of the directory holding your syncd.conf file to start the daemon script.
• By default, the script will create a .syncd.pid file for tracking the daemon process ID and a .syncd.log file to which the rsync output will be written.
• Arguments known are the ones known from initd scripts (start,stop,restart,status) as well as "run" for manually triggering a rsync and "log" for checking the rsync output.
