When you ssh to a sunos box it kicks off a script that mounts you a directory and enables ZSH.
I guess i could just get out of ZSH.
funny - when i echo the shell on the sunos box it says BASH, yet I am clearly in the ZSH shell.
The double bracket works on the SUN os boxes.
So I guess it is more of an issue with the version of bash than the shell i am using.
most of the linux boxes are 4.1 and the sun os is 3.0
