A shell one-liner for an infinite loop (sh/zsh/bash compatible)

sleep5.sh

while true; do date; sleep 5; done

@mhjb 👍

If you don't need to support sh then why bother with do and done?
for ((;;)) { date ; sleep 1 ; }
I find this one more readable because of curly brackets.

for ((;;))date&&sleep 1 even fewer bytes, in zsh at least :)

Just what I needed. Thanks!

@sergio-opslevel 👍

I've got nothing personal against zsh or bash, and I appreciate shorter scripts posted for bash and zsh. Still, maintaining the backward compatibility even in such a small script like in this gist is important.

Nice

And I thought indenting is a must like it's in python. Thank you so much!
