Here's an interesting (to me, anyway) little puzzle.
Background:
I have a process that restores a number of large(ish) files from tape backup. As an individual file is being written, it is owned by root, then the ownership is changed when that file is complete. Since this process can take some time (and operations, who actually runs it) isn't timely about starting it when requested or telling me when it completes, I wrote a little script to watch for the presence of the root-owned files:
So when I first kick it off, I set the sleep interval to something large, like 300. Then when I see files who are owned by root showing up, I cancel the script and resubmit with a sleep interval of 10.
So it occurs to me, could I code it to self-determine what the sleep interval should be. Check the outcome of the 'ls', and if nothing is owned by root sleep for 300, else sleep for 10. So, on first starting, there would be no files, so it would sleep for 300. On the first iteration that turns up a file, sleep goes to 10, and on first following iteration with no files owned by root, sleep goes back to 300.
