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++

virt-list-partitions

virt-list-partitions(1) 				      Virtualization Support					   virt-list-partitions(1)

NAME

       virt-list-partitions - List partitions in a virtual machine or disk image

SYNOPSIS

	virt-list-partitions [--options] domname

	virt-list-partitions [--options] disk.img [disk.img ...]

OBSOLETE

       This tool is obsolete.  Use virt-filesystems(1) as a more flexible replacement.

DESCRIPTION

       "virt-list-partitions" is a command line tool to list the partitions that are contained in a virtual machine or disk image.  It is mainly
       useful as a first step to using virt-resize(1).

       "virt-list-partitions" is just a simple wrapper around libguestfs(3) functionality.  For more complex cases you should look at the
       guestfish(1) tool.

OPTIONS

       --help
	   Display brief help.

       --version
	   Display version number and exit.

       -c URI
       --connect URI
	   If using libvirt, connect to the given URI.	If omitted, then we connect to the default libvirt hypervisor.

	   If you specify guest block devices directly, then libvirt is not used at all.

       --format raw
	   Specify the format of disk images given on the command line.  If this is omitted then the format is autodetected from the content of
	   the disk image.

	   If disk images are requested from libvirt, then this program asks libvirt for this information.  In this case, the value of the format
	   parameter is ignored.

	   If working with untrusted raw-format guest disk images, you should ensure the format is always specified.

       -h
       --human-readable
	   Show sizes in human-readable form (eg. "1G").

       -l
       --long
	   With this option, "virt-list-partitions" displays the type and size of each partition too (where "type" means "ext3", "pv" etc.)

       -t
       --total
	   Display the total size of each block device (as a separate row or rows).

SHELL QUOTING

       Libvirt guest names can contain arbitrary characters, some of which have meaning to the shell such as "#" and space.  You may need to quote
       or escape these characters on the command line.	See the shell manual page sh(1) for details.
