I am confusing why bash can escape "..." but can't escape '...'? Can some one give me a hint? Thanks

test@test:~$ echo "He said, \"Hello world\""
He said, "Hello world"
test@test:~$ echo "He said, 'Hello world'"
He said, 'Hello world'

Because that's how it's meant to be. See How to use a special character as a normal one in Unix shells? for the full details in various shells. – Stéphane Chazelas Jan 19 '24 at 13:35
You can concatenate adjacent quoted strings, so each type of quote can quote the other. Thus echo "single ' "'double " ' yields single ' double ". – Paul_Pedant Jan 19 '24 at 13:54

Is there some concrete issue here, some goal you're trying to achieve? – ilkkachu Jan 19 '24 at 19:03
