Why not use SGI's FAM (File Alteration Monitor)? It works under Linux...and I think I saw Solaris support somewhere. Under Linux, the FAM daemon doesn't use inefficient polling of the filesystem instead it monitors file changes through the kernel. Under Solaris, it'd probably fall back to polling.
If you can use it, then you can use the nice python-fam module. Very simple to work with and generally works very well. I wrote a python app that monitored a directory for file creation and deletion and sent emails based on certain events. http://python-fam.sourceforge.net/ Good luck. -- http://mail.python.org/mailman/listinfo/python-list
