How do I get a REPL in bash?

Question

I am learning bash and would think it would make things easier if i didnt have to keep saving a file, switching terminals and then executing that file. Is there a REPL in bash, sort of like irb for Ruby?

Answer 1

Make sure your login shell is bash. Open a terminal window. There, you have a bash REPL.

If your login shell is something else, open a terminal window and type bash.
