Kun-Yang Li,

If you want to check if a driver named jdem is registered you can use
the command:

  gdalinfo --format jdem

If you want to try opening a file in jdem format, then provide the name of
the file as the argument to gdalinfo.

eg.
   gdalinfo abc.jdem

I skimmed the tutorial and didn't notice anywhere it suggesting using
"gdalinfo jdem", but if there is a confusing part let me know and I'll
try and improve it.

Best regards,
