I just did that last weekend!

After an allnighter, which isn't easy for me anymore, I typed:

``rm -rf. /*``

with the dot and the space reversed.

When the shell threw an error in my face, I thought, "oh, an extra dot." so I deleted the dot and re-run the command.

And there goes my configs and most of the dotfiles in my home dir. Luckily, I have backup for some of those, so it wasn't a complete disaster.

I don't trust myself doing ``rm`` in commandline anymore.
