I set up a new home server recently using containerized services, and I wanted to share what I learned. Nothing here is revolutionary, but this is the type of resource I wish I had when I started.
I'm open to feedback on what I could have done better!
It lets you clear the bash command history, either completely or selectively. Here's the GNU docs for the history builtin: https://www.gnu.org/software/bash/manual/html_node/Bash-History-Builtins.html#index-history
(I'm not too familiar, someone else can clarify: is this available outside bash?)
What's interesting to me is the
-aoption, which lets you "flush" the history for the current session without ending the session. I can see that being useful!
