DOS Batch File 

 convert.bat::

  FOR %%F IN (*.*) DO gm convert -quality 90 "%%F" "convert/%%F.jpg"

Test File Integrity (from Bob Friesenhahn)

 * Extended the GM 1.2 development version a bit so a command like "gm identify +ping filename" can be used to force reading the entire file.  This is a good way to test for errors.  Normally only the file header is read if possible. (This feature is not in 1.1.7.)

Example::

 % gm identify +ping grace-tongue-out.jpg 
 grace-tongue-out.jpg JPEG 7400x7560+0+0 DirectClass 8-bit 17.3m 8.460u 0:09 (6.3m pixels/s)
