in reply to ExifTool & system()

Okay, so now I change the calls to be like so...

# Extract main (left) image. qx|exiftool -trailer:all= $mpo -o L.jpg 2>&1 1>/dev/null|; print "ExifTool error on image 1: $?\n" if $?;

...and now get feedbacks of...

...and yet STILL the program works!


Admittedly my present job has kept me long away from Perl. I use it but seldom now and so have grown rusty. Once I had used to sometimes answer for other people in the same way my own questions had once upon a time used to get answered. When I knew how to do it, I would answer thus, saying...
