Aah.  I forgot about the meanings of various quotes in bash.  That's an 
excellent example.

plink also allows commands to be run.  That "bash -l -c 'commands'" 
works great.  I see if there's any way to change the code to use it, but 
that solves my problem.

Yup.  Thanks.

I guess I didn't know the original PATH was the windows one.  That makes 
more sense now.  So I'd see the same thing on a Linux box using pure 
ssh.  If the PATH were changed by /etc/profile, and I didn't use the 
"bash -l -c 'commands'" stuff to force a bash login, then I wouldn't see 
the new PATH there either.

I assume that the only way to 'source /etc/profile' requires a change to 
the content after "ssh a AT b".  For example, '"ssh a AT b bash -l -c 
'commands'" and "ssh a AT b source /etc/profile; commands" both work for 
me.  I only wish I could "ssh a AT b commands" and have it work.  I've got 
the info I need to figure out a different solution, though.  Thanks!

It helps immensely.  Thank you very much.
