  Uh, it's a shell script *containing* a single ssh command.  Note the
shebang.  Also note the mention of the filename "test.sh", which is not to be
confused with the script "start.sh" on the remote machine.

  Surely not, if you want the definitions to be visible in the sub-shell that
executes "start.sh"?

  Surely not, unless /cygdrive/c/apps/bin is the qa user's home dir?

  Surely not, if it's a bit of debugging trace that lets ZW know that the
directory exists and so the cd command succeeded and there must be something
else wrong if the script doesn't execute?

  Ok, I'm with you there :-)  But I still think one of us needs more coffee...
