I'm learning the shell. I experiment with test cases in "MATE Terminal" The "up arrow" key is useful to recall previous command for editing.I hadn't expected it when I found all instances of "MATE Terminal" share same history.
*HOWEVER* I found that history remains after a "power off", "boot" cycle.
That is *UNACCEPTABLE* for my purposes. To start FRESH was the purpose of "power off", "boot" cycle. BUG? Workaround? TIA
