I develop and maintain free software in my spare time. Most of the software packages available here are for Apple's Mac OS X operating system. They are distributed as free, open-source software under the terms and conditions of the Free Software Foundation's GNU General Public License. Some of them are on my GitHub account if you feel like lending a hand.

That being said, if you find my software titles useful, please consider making a donation. I rely on your support in improving them and developing new ones.

Sentinel is a Mac OS X application which faciliates monitoring and observing command output. By allowing the process output to be monitored with periodic execution, it becomes easy to observe changes over time. In a way, Sentinel is similar to the watch command line program, but includes additional features, such as diff-ing output with previous output and colouring lines of output that have changed.
