use incrontab to run a cron job when anything under a directory is modified using *

Question

how can I tell incrontab to run this command when there has been any modification done under the /web directory?

/web IN_CREATE,IN_DELETE,IN_MODIFY /bin/echo "this is a test..."

Just a hint: `/bin/echo` will not be connected to any terminal so the output goes nowhere (but you will get a info line that the action ran in the syslog). — Sven, Feb 06 '12 at 13:44
+1 Your syntax looks right. Is it that you just don't see "this is a test..." displayed? — Richard Holloway, Feb 06 '12 at 21:25

Here is the incrontab record syntax taken from this page:

<directory> <file change mask> <command or action>  options

So, your command should be OK. You need to pay attention to two points:

Add the needed changes in the record such as the mentioned in your question (IN_CREATE, etc...).
This record will watch only the directory the files/folders under it, but not under its subfolders. It is NOT recursive. You need to include more records if you want to watch other subfolders.
