I include precautions so the script tries to validate the device as an USB device, but that's not a substitude for user error!

Simple script to create a bootable usb from iso with dd

If you are like me, can't remember the dd command to create a bootable USB and always have to google it again, then this is handy to have..

Usage

sudo ./ddusb.sh /path/to/some.iso

Sample output

Identify the USB device:
sdf                   8:0    1   7,5G  0 disk
├─sdf1                8:1    1   2,3G  0 part /media/username/Ubuntu 19.10 amd64
├─sdf2                8:2    1   3,9M  0 part
└─sdf3                8:3    1   5,2G  0 part /media/username/casper-rw

Please enter the USB device identifier noted above (e.g sdf)
Identifier: sdf

Please verify that all input is correct:

ISO file: /path/to/some.iso
USB device: /dev/sdf
dd will be: dd bs=4M if=/path/to/some.iso of=/dev/sdf status=progress oflag=sync

Is the input correct? [y/n]: y
