How do I escape spaces in bash environment variables as an argument?

Question

I have an environment variable that contains flags and arguments eg

export CMD='compile -m bla --vars "hello there"'

When I try to run run ${CMD} , the error says:

error: unrecognized arguments: there"

It doesn't register that the quotation belongs to "hello there". How can I escape this?

Can try to use backtick. A backtick is not a quotation sign. It has a very special meaning. Everything you type between backticks is evaluated (executed). Attection is executed before the main command

hope it helps you in your problem
