Anyone know why the old csh is now codice non grata ? And what's so freakin' hot about zsh ? [View all]

OSX and Manjaro have both defaulted to zsh and I can't invoke csh anymore in Manjaro -- it doesn't even seem to allow a d/l of csh. (OSX lets me use chsh )

(I know, csh on OSX is really tcsh, a superset of csh).

I'm used to running long, resource-greedy jobs in bg -- just add "&" after the command and then logout of Terminal. In zsh, this kills the job whether you want it to or not.Just trying to bg a process in zsh requires a couple of pages of reading. Who asked for that ?
