set built in command

I recently ran into a situation where the vi editing style for command line was set in /etc/profile.  Being used to what I thought was the “standard” line movements for Bash, I discovered that it was actually the standard line movements for emacs.

The set -o only takes on of 2 command line editing interfaces, emacs or vi. So to “undo” the vi editing style just add a set -o emacs in your .bash_profile.
