I would like to run a script upon the creation of a directory with a particular name. While I could use ‘find’ or ‘locate’ on a cron that seems rather inefficient. Is there a way to ‘hook’ into the creation of a file or directory with a script?
I think there must be a way since ‘locate’ keeps its database up to date all the time.

as far as i know ‘locate’ keeps its db up to date using ‘updatedb’
being triggered by a [default] once a day cron…
have you changed yours to an “all the time” cron…wouldn’t that cause
a huge resources hit and drag your system down? [of course, your
system might be strong enough to do it constantly…mine would not be!]
I’ve done nothing special with updatedb but locate seems to be up to date without me ever running updatedb so I just figured the SuSE people did something extra that is perhaps not so easy to find in the documentation.
In my case if it was on a cron, as long as it wasn’t being run too often it probably wouldn’t slow me down too much with a quad core 2.6 GHz processor. I find the quad core pretty much keeps the system smooth even when some process sucks up 100% of one of the cores on a thread and I have never seen Linux allow something to push more than one thread to 100% (although I am sure it is possible).
Usually they all just sit there and fluctuate between 1% - 10% usage or less if I close the system monitor and use something text only like htop.
