[solved] Backspace key broken when running as root
I've installed Void Linux base image and my backspace key is broken when I am root, it types '^H' instead of erasing. Function keys also type something weird, but at least the brighness-related ones do work.
This only applies to the root shell, it all works perfectly when I login as a normal user. Probably a bashrc issue?
UPD: I typed 'stty erase ^H' in the shell and it now works.

Super users don't make mistakes.
[Solved], but what was your solution 👀
Yeah, probably a .bashrc difference between users.
It could also be ~/.inputrc (or /etc/inputrc if not in the user's home directory.) https://man.archlinux.org/man/readline.3
Probably a locale issue
Yeah I’d bet this. Had my keyboard set to GB something once and backspace and tilde were all messed up
What does
$TERMsay for both users? I assume you use Bash for both users?It says "linux" for both. You're right, I'm using bash
This is one of those issues where there's a billion different solutions based on a billion different reasons.
Have you compared the configuration files? You most likely have some keybinding that root don't have, and hopefully works for root as well.
I noticed this as well on Void, but never really looked into the cause, but like other people pointed out, the root user must be lacking some shell-related configuration or something. For me tab-completion and up arrowing through the command history was also broken for root. It frustrated me, but never enough to bother trying to solve it lol.
You might also have a look at
stty --alloutput:erasein particular.It says 'erase = ^?'. How do I change this?
What is it when you're root?
What is it when you're not root?
What does the command
stty erase ^Hdo?Is it possible to set this permanently?
Sure, but there are many ways to do it, depending on all sorts of details/variables, like what terminal or terminal emulator you are using, what shell, etc.
Consistent BackSpace and Delete Configuration has lots of information that might help you understand the relevant details of your system and options for setting it as you wish for root.
stty situation indeed
