So I'm doing a simple inotifywait loop to watch for changes in a Bootstrap directory:

while inotifywait -r -q --format %w bootstrap/; do

    echo "something happened"

    [[ $filename == *.js ]] && uglifyjs .....

    [[ $filename == *.less ]] && lessc bootstrap.less

done

You don't really need to worry about the internals but I just can't get the filename back into a bash scope. inotifywait echos out the filename (with help from the format argument) but how do I capture that and use it later on (in my case, as $filename)?

If you want a simple, short test harness:

touch testfile

while inotifywait testfile do; echo "..."; done

And then you can just run touch testfile when you want to trigger it.
