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.
