in reply to No command window output when running script

`\"$tf\" labels /owner:theOwner \"$buildLabel\"`;

I think it's just that backticks returns the output, rather than prints the output ... and since you haven't collected what was returned, it just gets lost.
By way of demonstration:
C:\_32\C>cd C:\_32\C C:\_32\C>perl -e "`cd`" C:\_32\C>perl -e "$x=`cd`;print $x" C:\_32\C
Cheers,
