When I am on a non-root user I cannot use ↑/↓ to list my previous commands, and if I am typing I can't use ←/→ to say, add in a directory or to correct the spelling.
Worse, I can't use Tab. I could write
/var/www/mylongsitena and pressing Tab will not autocomplete it.
It's extremely annoying. How can I change this? IIRC Debian etch and lenny didn't do this. How can I unto this change?
