monitor directory events

pbillast · #1 (**permalink**) 07-02-2009

I'm am looking for a cheap way to trigger a script when a new file is written in a specific directory. AIX 5.3. It is a production system, so no kernel patching (i.e. inotify).
Filemon and audtiing are too expensive.
Thanks in advance.

cronjob checks for the file, if it's there run a script

cronscript.sh:

Code:

if [ -f /yourfile ]
then
yourscript.sh
fi

crontab -e

Code:

* * * * * /cronscript.sh >/dev/null 2>&1

to look for new files in a directory::

something like

Code:

find /directory -cmin -1 -type f -exec /yourscript.sh {}\;

in your script use the $1 variable and do something with the file
Edit:

forgot to say, when using ctime, a file will be processed again when it's modified too, so you should move them elsewhere after first procesing

thanks but I was looking for something that traps the events instead of checking via cron
