I did switch to fish, once upon a time. But as I barely understood bash, that was probably a mistake. Anyway, I just want to endorse Dan's idea:
create shells cash, trash, theclash, and bangersandmash.
That is all.
My DropBox bill is going up, and while I get value from it, I wonder whether there might be alternatives. I don't think I want to be responsible for hosting something like NextCloud, but I'm willing to be persuaded. Could anyone who has done so offer an honest appraisal. Thanks.
