Although dash is lite and simplified edition of bash, It doesn't support arrow key to move the cursor position. In order to improve performance, a lot of feature in bash are removed in dash. Add arrow key support will not cost too much performance. Currently it dash is like that: ```sh $ echo hello hello $ echo ^[[D^[[D^[[D^[[D^[[C^[[C^[[C^[[C^[[A^[[A^[[A^[[A^[[A^[[B^[[B^[[B^[[B^[[B $ ^[[D^[[A^[[C^[[B^[[D^[[A^[[C^[[B^[[D^[[A^[[C^[[B ``` The cursor won't move but only append unexpected character.
This is configurable. When dash is built with libedit support (configure --with-libedit), and the emacs or vi option is enabled, libedit is used for entering commands which will handle this (and more).
