P.S. - I should note that, in the posted example for mdutil -
! BUILD THIS SCRIPT:
! sudo mdutil -E-s /Volumes/Jurassic\ Grad\ -\ Spare\ Change/ >
/Users/cwalston/factor/mdquery-results.txt
! EXAMPLE:
! "/Volumes/Jurassic Grad - Spare Change" md-re-index
- there is an issue intercepting the authentication prompt required by
sudo. I actually got
a response after running the command-line directly in my shell, to see what
was going on...
Any suggestions as to how intercept this authentication prompt?
