     Type:  defect           |     Status:  new
 Priority:  Normal           |  Milestone:
Component:  ports            |    Version:  2.1.2
 Keywords:                   |       Port:  fish
-----------------------------+--------------------------------
 Changing directory to parent or another one (without cd) with this
 approach:
 [[BR]]
 $ ..
 [[BR]]
 $ ./another_one
 [[BR]]
 works great.
 [[BR]]
 However if you made a mistake and instead of ".." try to call ".":
 [[BR]]
 $ .
 [[BR]]
 fish will freeze. And nothing you can do with current terminal.
