Racket - how to get the “previous executed command” in bash script?

问题

Is there any keyboard which echoes to the screen the "previously executed command"? Something like the up-arrow key at Linux bash...

It's not duplicate to How do I get "previous executed command" in a bash script?

回答1:

Load XREPL and you'll get readline-style input editing, which should include the ability to load previous lines using the up-arrow key.

(require xrepl)
