A coworker once asked me for shell tips. I gave them a few that came to mind, and also invited them to peruse my .bash_history, because I figured there might be other tricks hiding in there. They later asked why I sync all the time, almost always in threes. "Huh?" Looking through history, I see that I do. Apparently it's been ingrained into my subconscious, like a sort of stutter, and I type it sometimes out of habit when I'm deep in thought. Old habits really do die hard.
