Backspace not working

backspace not working

Where isn’t it working? A bit more info would help me here.

in all terminal like linux playground or terrafrm playground, generally arrow key and backspace key not working

Are you refering to in vim, or generally in the terminal? I’ve never seen this myself, but there are vim configurations that can be troublesome.

its in only general terminal like all terminal,ansible,terraform linux in all playground not inside vim editor

its working ,thanks for your time
