If you use the command "set -o vi" in /etc/bashrc or in /etc/profile, then command-line editing doesn't work. If you try and use one of the VI command to scroll through the history list such as ESC-k k k, you just get a beep. If you remove the "set -o vi" command from /etc/bashrc and /etc/profile, and then type in the command from the command line, then it works fine. When the command is in the rc file, and you type "set -o emacs" at the command line, then the emacs mode works. If you then attempt to switch to vi mode "set -o vi," then command-line editing fails.
