Hi all, I am using debian testing, and the bash version is 3.1.5. I have the following lines in my .bashrc to assign arrow keys to history search: bind '"\M-[A":history-search-backward' bind '"\M-[B":history-search-forward' It worked well before, one day, after I did a routine upgrade, it stopped working. The weird thing is, the arrow key search still works in a sudo shell. Anyone has a clue on what's wrong? Many thanks. Lei
