From the Arch Linux Wiki: https://wiki.archlinux.org/index.php/USB_flash_installation_media
# dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx status=progress && sync
[...] Do not miss sync to complete before pulling the USB drive.
I would like to know
- What does it do?
- What consequences are there if left out?
Notes
dd
command used with optional status=progress
:
tar -xzOf archlinux-2016-09-03-dual.iso | dd of=/dev/disk2 bs=4M status=progress && sync
Or using pv
for progress
tar -xzOf archlinux-2016-09-03-dual.iso | pv | dd of=/dev/disk2 bs=4M && sync
