Hi, You may want to look into inotify-tools, in particular inotifywait. You can use it to monitor a list of files or optionally recursive directories for changes and do something like: while true; do inotifywait <file> ...; make check; done If the list of files is very large, the set-up can take a long time (several seconds for tens of thousands of files). In that case, you may want to write a smarter script with "inotifywatch" that has the set-up cost only once, and then you just monitor inotifywatch's standard output. If your list of files is extremely large, then you may run out of kernel memory or the user limit on inotify watches. In the latter case, you can increase the limit in /etc/sysctl.conf (the relevant variable is fs.inotify.max_user_watches). In the former case, you really have a very large file list and you may want to restrict it to your current working set. I hope this helps. Pippijn
