This is not working for me! Will someone clarify why?

Here's the command I'm using:

hdiutil convert -format UDRAW -o /Users/Jacob/Desktop/destination_file.img /Users/Jacob/Downloads/debian-8.2.0-amd64-DVD-3.iso

And here's what terminal returns:

Usage: hdiutil convert -format <format> -o <outfile> [options] <image>
       hdiutil convert -help

    man hdutil only lists four character formats - however it also has the image as raw first parameter so could be wrong – user151019 Jan 19 '16 at 13:26
  • Unfortunately, almost every Q&A forum has this posted as the way to convert an ISO to IMG in order to create a bootable USB for Linux OS installation. If you have a more effective method, please elaborate. – rbApostate Jan 19 '16 at 13:36
  • What does UDRAW stand for and which site shows this - googling gives me lines using UDRW as per man page – user151019 Jan 19 '16 at 13:43
  • @rbApostate The raw img format you mention is an image of a real CD including the CIRC data (similar to the bin/cue files). It doesn't make any sense to convert an iso to an img file because the source is no physical CD. – klanomath Jan 19 '16 at 13:56
  • @rbApostate, Did you try running hdiutil convert -help as the Usage output shows? It shows the proper Usage and Image Formats to form a proper command line. – user3439894 Jan 19 '16 at 16:01

The proper command to use is:

hdiutil convert -format UDRW -o /Users/Jacob/Desktop/destination_file.img /Users/Jacob/Downloads/debian-8.2.0-amd64-DVD-3.iso

(source with an OS X how-to)

In UDRW RW doesn't stand for RAW but for R/W (readable and writable)!
