TLDR: This works:
( (
bar
foo
) 1>&- 2>&- & )
So, basically, what this does is run a sub-shell then bury your commands in another sub-shell and closes all STDOUT being reported and is sent to the background. I honestly am still not sure how this works!
&!
Because I use shellcheck with my zsh scripts the following flagged an unknown error in shellcheck (because shellcheck does not support zsh at the moment) and it wouldn't lint the file:
() (
foo
bar
) &> /dev/null &!
Specifically it was the &! that wasn't working (but is a valid ZSH directive to suppress background output). I would always get job output at the least using most of the suggestions e.g. on Stack Exchange. So, I went down a Googling-rabbit-hole with no answers, until I landed on:

Which I then had to grok the horrible formatting and came up with the above that is Bash compatible to run commands in the background with no output!

Another update to use
) 1>&- 2>&- & )today, as I still was getting output! See cyberciti.biz/faq/how-to-redirect-... on why I chose this. Really it's because it seems to just be working :)Updated to use
