This first part of the script is supposed to get the total size of the disk image when mounted:

Code:

os=0
for i in ${DMGLIST[@]} #This array contains a list of .dmg files
do
    DMGSIZES[pos]=$(hdiutil imageinfo -plist $i | awk -F"[<>]" 'a{print $3; exit}$2=="key"&&$3=="Total Bytes"{a=1}')
	let pos++
done
unset pos
echo;echo

This part of the script restores images to their corresponding partitions. The size of the partitions is based on the total size of the mounted disk image.

Code:

a=0

for i in ${DMGLIST[@]}
	do

	echo "Reimaging the "${DMGLISTshort[a]}" Partition..."

	asr --source "$i" --target /Volumes/"${DMGLISTshort[a]}" --erase --noverify --noprompt --disableOwners
	sleep 2

	let a++

partx

PARTX(8)						      System Manager's Manual							  PARTX(8)

NAME

       partx - telling the kernel about presence and numbering of on-disk partitions.

SYNOPSIS

       partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk

DESCRIPTION

       Given  a  block	device	(  disk  ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or
       remove partitions.

       This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering
       of on-disk partitions.

OPTIONS

       -a     add specified partitions or read disk and add all partitions

       -d     delete specified or all partitions

       -l     list partitions. Note that the all numbers are in 512-byte sectors.

       --type TYPE
	      Specify the partition type -- dos, bsd, solaris, unixware or gpt.

       --nr M-N
	      Specify the range of partitions (e.g --nr 2-4).

SEE ALSO

       addpart(8), delpart(8), fdisk(8), parted(8), partprobe(8)

AVAILABILITY

       The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
