What system/shell are you running on. I tried the commands above under unbuntu linux, it just gave me errors.
$ mkdir folder
$ mv folder $something_that_does_not_exist
$ mv: missing destination file operand after `folder'
Try `mv --help' for more information
$ touch files1 files2 files3
$ mv files* $something_that_does_not_exist
$ mv: target `files3' is not a directory
Of course if $something_that_does_not_exist is defined then, it will move your files to whatever the value of $something_that_does_not_exist is. You can find the value of $something_that_does_not_exist by typing:
$ $something_that_does_not_exist
If that command returns nothing, then $something_that_does_not_exist
it is undefined. If that command prints a value, that value is where you moved the files to.
I'm thinking this may be a joke question. Can others confirm this actually happens?
