To monitor a file in linux, I can use inotify-tools like this
#!/bin/bash
# with inotify-tools installed, watch for modification of file passed as first param
while inotifywait -e modify $1; do
# do something here
done
but how would I achieve this in OSX?
If you want to wrap this into a Python script, you can use Watchdog, which works with both Linux and OSX.

Here is what it looks like to replace pyinotify with watchdog:

Watchdog also has a shell utility called watchmedo
:
watchmedo shell-command \
--patterns="*.py;*.txt" \
--recursive \
--command='echo "${watch_src_path}"' \
.
Yes, you can use the FSEvents API
You can use entr
tool. Example usage:
ls some_file | entr do_something
On Mac install via Brew: brew install entr
.
