*nix shell: stty for terminal line settings

leave a comment »

I don’t think this is a new discovery but just a reminder for myself when I encounter this problem again.

I encountered this problem when I was using irb (interactive ruby shell) and for some odd reason when I typed backspace it was printing ^H and worse when I hit enter irb crashes. When I returned to my shell backspace seems to be working fine.

This is not exclusive problem with irb although the crashing part is but the solution I think would work in cases where shell is demonstrating this wierd behavior.

I did a quick *nix command:


and displayed that I have

erase ^?

In order to fix this problem here is what I did:

stty erase ^H

Note:^H are not the two characters but typed Ctrl-V Ctrl-H
