"open" from the command line just hangs using iTerm2 The 

open -a &lt;AppName.app&gt;


is not working on one of my Yosemite based macbooks. The other one - also with Yosemite - works fine.

open -a TextEdit.app ~/out

(just hangs )


I have also tried other apps - to make sure the problem were not specifically with TextEdit. Nothing works.  Also I am able to use Finder to open apps with TextEdit.

AFA the app's attempted:  let us look at a simple built-in one: 

 $open -a TextEdit.app ~/out


Note that "open" has not been disturbed in any way: it is the one shipped with the MacBook

ls -lrta $(which open)

It appears the issue were rather with iTerm2.   I tried the same commands on Terminal and it worked fine.  I do need some of the features of iTerm and am investigating which version(s) actually work. The one I am using (and does not work) is the one on the Download link.  So far I am having better luck with their iTerm 3.0 Alpha version.
