More of a curiosity/educational question. I have been using etcher for a lot of my raspberry pi projects and am very happy with it. I’ve been curious as to what commands it is running in the background. I have tried using a combination of Mac OS diskutil, dd via brew, and dcfldd via brew. Although, I have not be able to get my images to run on the pi as consistently as etcher.
I have tried and am currently using the etcher cli (Thank you for that!) , but was also curious to see if i can write a quick script to replicate it as well in bash on my computer. I have tried the following:
eval "sudo diskutil eraseDisk free UNTITLED $device" eval "sudo diskutil eraseDisk FAT32 RASPBIAN MBRFormat $device" echo "Unmounting the disc in prep for image burn" eval "sudo diskutil unmountDisk $device" sudo dcfldd if=$IMAGE_NAME of=/dev/disk2 of=/dev/disk3 bs=4M statusinterval=1 sizeprobe=if echo "External drive Found: $device: Mounting Disk" eval "sudo diskutil mountDisk $device" echo "adding .ssh file here" echo "Ejecting the disks now..." eval "diskutil eject $which_disk"
Any guidance would be appreciated, I’m sure its something small that I’m missing.
