Curiosity... :)

Hi,

just stumbled across this:

Doing

    /home/user/>..

let me jump a directory in direction to the root.

But doing 

    /home/user/>.

gives me:

    .: not enough arguments
    zsh: exit 1

instead of 'beamed up'...but...
Scotty got problems...or?  ;)

Best regards,

You apparently have the AUTO_CD option enabled.  The description of that 
in the zshoptions(1) man page is:

  If  a  command is issued that can't be executed as a normal command, 
  and the command is the name of a directory, perform the cd command to 
  that directory.

There usually isn't a '..' command, but there's always a directory with 
that name, so that rule kicks in.

But '.' is a builtin command name, so that command is run.  Since that's 
the first thing to be tried it doesn't matter that '.' is also a 
directory name.
