Hi vgersh99,
Ouch. Yes, you're right that was a command substitution; not a variable expansion. (I do know that I need new glasses and I have an appointment with my ophthalmologist Tuesday morning.)

But, just like a variable expansion, if the <dollar-sign> isn't escaped in a command substitution, it will be performed by the local shell; not by the remote shell.

I guess seeing echo $(pwd) I interpreted it as echo ${pwd} instead because pwd would be so much easier and would be interpreted by the remote shell instead of by the local shell (true for variable expansion and for command substitution). I apologize for any confusion my comments may have raised.

Sorry,
Don
