Has anyone executed antsetenv.sh on latest version of macOS Sierra?

When I execute . ./setantenv.sh .

I'm getting;
.: Command not found.

If I try to run as:
source ./setantenv.sh

I am getting:
OWN_NAME=setantenv.sh: Command not found. OWN_NAME: Undefined variable.

I've not seen this happen on previous versions of macOS / OSX.
This is on hybris 6.x
