That is a nice and simple way to get the date and time compared to monster
I was working on...

No, I don't. Not sure how that got there in the first place as ~ isn't even
close to " or / on my keyboard.

No, but a hardlink (ln without -s) or cp would do it.

I didn't consider that an option at first because I have several different
people running the program at random times and I didn't think I could count
on them remembering to start using a new command to start it. Now reading
this I had an idea that I could rename the original executable and make the
script with the original name. I think that is what I will do.

Thanks for answers. I went with a different implementation although I am
still curious if it is possible to do what I was thinking about first.

~ is an abbreviation for the home directory in most shells. So in Perl
that would be:

$ENV{HOME} . strftime("/foobarlogs/foobar%Y-%m-%d-%H-%M-%S.log", gmtime);
