Ahm, I don't think you can, since the shell is sending to STDOUT in
this case, and STDOUT has been redirected at *shell* level to be
someplace other than STDOUT; in this case, a file. The script has no
knowledge of what's going on here. It's simply dumping to STDOUT.
You're best bet is to have your output structured the way you want to
see it, then redirect it.
Or, have your shell script take a command line option to specify an
output file. Test if this option is used, then format accordingly.
Hope that helps.
