Checking file existence

I have files that are named in the following manner: file.####.jpg (where #### is an hhmm timestamp [hour and minutes]) What's the best way to take the current hhmm timestamp and run backwards finding the previous 5 files, and checking whether they actually exist? There's a possibility one or more might not exist and rather than returning a blank value, I want to continue further back till I find the next. So for example, say I have: file 1122.jpg file 1121.jpg file 1119.jpg file 1117.jpg file 1116.jpg file 1114.jpg Notice the gaps, 1120, 1118, and 1115 are missing. But I still want to return five, thus 1122, 1121, 1119, 1117, and 1116. I thought of taking the current timestamp and loop five times, subtracting from it every time, but that's assuming all five are there. If one's missing then I only have four images. -- W | It's not a bug - it's an undocumented feature. +-------------------------------------------------------------------- Ashley M.
