  1. Here’s the corrected command:

    hdiutil resize -size `hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk ‘{ print $1 }’`b /tmp/Mavericks.sparseimage

    It had an apostrphe vs the right character.

  2. Nope, still doesn’t work, even with the commend correction
    “hdiutil: resize: unable to read -size parameter in “b””

  3. The correct code is this line to make the hdiutil: resize work:

    hdiutil resize -size `hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk ‘{ print $1 }’`b /tmp/Mavericks.sparseimage
