Detecting incoming files without busy polling
Hello, I'd like to handle incoming (uploaded) files from a shell script, ideally without busy polling / waiting (e.g. running a cron task every 15'). Is there a command that would just sleep until a new entry has been created in a directory, allowing scripts such as the following: Code:
while watchdir $SOMEDIR
do
# process new files here
done
The "watchdir" command should ideally only wake up when the new entries aren't being used (or at least written to) by anyone, so the file can safely be handled. This will have to run on HP-UX, but I am interested in linux alternatives, or even pointer to the underlying API or system call. Thanks. |
