Package: zsh Version: 5.8 When I type `echo 'Hello!'`, it prints `Hello` but when I use double quotes instead of single quotes, there is no output and the shell waits for the quote to end. Here is a transcript!
$ echo 'Hello!' Hello $ echo "Hello!" dquote> I suggest that the shell should recognise the quotes. I am using Ubuntu 20.04 and kernel 5.15.0-52-generic.
