watcherd | shell daemon that will listen for directory changes

watcherd is a Shell library. watcherd has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

watcherd will look for directory changes (added and deleted directories) under the specified path (-p) and will execute specified commands or shell scripts (-a, -d) depending on the event. Once all events have happened during one round (-i), a trigger command can be executed (-t). Note, the trigger command will only be execute when at least one add or delete command has succeeded with exit code 0. If you need the same functionality to monitor changes of listening ports, check out watcherp.
