seeking howto run script when various events happen
 

Is there an existing utility {suite} that will let me do the following:

• on mount {filesystem} run {script}
• on un-mount {filesystem} run {script}
• when {folder} content changes run {script}
• when {file} content changes run {script}
• on connect to {SSID} run {script}
• on disconnect from {SSID} run {script}
• on connect to {ethN} run {script}
• on disconnect from {ethN} run {script}
• ... and so on ...
• cron handles time and date based events

I'm hoping for something that is more like cron than systemd.

I used to see all sorts of articles about this sort of thing but then we got more and more-complex subsystems doing action-on-event processing and the end-user options for doing this are not as obvious -- to me.

Thanks in advance,

I'm not aware of anything that will do it all .. there are several tools that can handle parts such as inotifywait for directory content changes and plugd for network connect/disconnect

Maybe we should start a small project ..

If there are multiple tools, each that handle part of my requirements, we might need one project "... to rule them all, and in the darkness bind them ..." (sorry)

Sadly, I think that the 'systemd' folks have already co-opt-ed the do-everything when events happen problem. I'm interested in end-user, get-my-work-done, user-level do-something-on-event processing.

I'll draft a Blueprint document...

Thanks for the reply,

I finally -- FINALLY -- found a solution to what I want to do.
Use INCRON for actions

I have not made this work like I want ... yet ... but it should meet my requirements based on what it written on the tin.

Thanks, again,
