bash scripting request

[Barry R Cisna]

Hello All,

Can someone here that is into bash scripts give me some insight on how
to accomplish the following?
Our school is in talks of possibly at least partially going to Chromium
os for the next school year. I have built a few 32-bit and 64-bit dev
images and have done several hours of testing at this point.
When using the dd if=myimage of=/dev/sd# bs=4MB the images are taking
almost 15 mins to build on to each usb stick.

Can someone post here,,possibly how to run a shell script that would
contiguously write dd to say all of the inserted usb sticks,in each of
the 8 usb ports of my build bot host machine,with omitting of
course,,the actual hard disk of the build bot machine?

Thank You,
Barry

SteveG,

Thank You for the link for mdcp package. This is exactly what i was
looking for. Never heard of this utility before.
Now I just have to remember when I am in a hurry, and when running it I
do not use /dev/sda(host machine hdd) as a target device to write
to.,,Wipeout!
Don't ask me why i am saying this,,,:)

Thank You,
Barry

I haven't used it to image USB drives but I'd expect clonezilla-live
to be good at it. It knows enough about filesystems to only copy the
used blocks.

Barry, I do not code much at all but it seems rather simple.
First, make sure you know the name the devices when mounted.
Then you check for it with an if statement: if device is mounted , do
dd..... fi.

This link can point you in the right direction:
