Shell script to download files from s3

My independent spirit served me well in those days. It taught me to get stuff done and guided me to higher paying employment opportunities.

You may need to install a random number generator: that'll be apt install rand on Ubuntu. That worked fine as long as I didn't happen to receive more than one batch of messages on the same day. If I did, then the new messages would overwrite older files in that day's directory. I guess it's mathematically possible that my rand command could assign overlapping numbers to two files but, given that the default range rand uses is between 1 and 32,, that's a risk I'm willing to take. At this point, there should be files in the new directory with names like email, email, etc.

There are currently no files in tmpemails - that's because the mv command moves files to their new location, leaving nothing behind.
