Fair enough. We once had a security webcam gadget ftp'ing images into a
directory every minute, 1440/day, but a php script listing the files for
display was timing out just on the 'ls' when over ~2000 files on a 2.4G
P4, prompting better (in that case, directory per day) organisation.

That was off the top of my (then tired) head, and will of course barf if
'comp' appears anywhere in a filename; it should be 'grep -v ^comp'.

That's the extent of my awk-foo, see Giorgos' post for fancier stuff :)
And thanks to James for the base script to bother playing with ..
