Sure.  Consider that the pipe is not created by bash, but by cmd.  What
you get is the exitcode of the last command in the pipe, which is tee.

Sure.  You're using the -c option, so you're trying to run mainScript.sh
as a command.  I assume mainScript.sh is in the current working
directory.  And the current working directory is not in $PATH.  And it
shouldn't.  Either use ./mainScript.sh or, better, the full path to
mainScript.sh since that makes you independent of your CWD.
