What problem are you trying to solve? That is, *why* do you want to do that?
If you're trying to do something that isn't driven by comparing
timestamps on files but rather is simply an iterative process, then a
simple shell script may be a simpler and less confusing solution.

This rule is wrong: "To update *any* file ending in ".txt", touch the
file ${RUN_COUNT}.txt." So if RUN_COUNT=1, then if you want to update
foo.txt, touch 1.txt. If you want to update sldfjsldkf.txt, touch
1.txt. How can that work?
