I really like this, replace compile with whatever command you desire I guess.

This is a terrible solution. You will stress your IO for no reason.

On the upside, you do not need to install the inotifywait package. md5sum already installed on my system haha

If you are a big fan of wasting disk performance, CPU cycles, and ultimately power.

I do not need to install anything/can work on bare install without internet connection?

[–] nublug@lemmy.blahaj.zone 1 points 10 months ago

ah, fair.

You should be able to tie into the kernel with some C programming if you want to go extra small.

It isn't a terrible solution if you are checking infrequently just as ever 30 minutes.
