I would just have a script with either all the variables on top of the script for you to set, or have it look for them in a configuration file you might change a little every run. That’s just my preference for this sort of thing, though. If I can avoid using external stuff or spending time learning new syntax, and keep it as simple and stupid as possible I try and just do that. Sounds like your solution is simple enough with shell history file keeping a record for you. Maybe playing with aliases or writing functions in your bashrc could save some typing for you
