We make very careful considerations about the interface and operation of the GNU coreutils, but unfortunately due to backwards compatibility reasons, some behaviours or defaults of these utilities can be confusing.
This information will continue to be updated and overlaps somewhat with the coreutils FAQ, with this list focusing on less frequent potential issues.
Good tips and reminders for those who don't work mostly with a CLI (Command Line Interface).
[What has been YOUR biggest CLI gotcha? -Ed.]

Sorry, was from another one of this dude's pages--forgot the link: http://www.pixelbeat.org/docs/power_of_the_default.html [pixelbeat.org]
While I'm at it:
tail -F is probably what you want rather than -f as the latter doesn't follow log rotations etc.
That's a "Gotcha?" I've been using "tail -f" for about two decades and only needed to tail a rotated log file once, ever. And the man page tells you exactly how to do it.
