Graybeard here (never thought I'd say that). 25 years of unix/linux in production systems.

Changing the default behavior of a posix command is a footgun.

If I wanted to get help from mv:

    $ mv --help
    Usage: file [OPTION...] [FILE...]
    Determine type of FILEs.
I get the help for the file command.


And this is _exactly_ why, although this is cool, it would have been cooler had it been renamed to, for example, `imv` (aka the name from the rename tools project ;-) )


This is also why I cringe when people suggest to alias `rm` to `rm -i`. That will bite you, believe me.


heh :) youre right
