Bootiso is a powerful Bash script to easily and securely create a bootable USB device from one ISO file. It helps you create a bootable USB from an ISO with a single command from the terminal. It is a well tailored script that carefully organized and validated using shellcheck.
It has to be run with root authority, and if external programs it requires are not available on your system, it will ask you to install them and exits. Bootiso checks that the selected ISO has the correct mime-type, otherwise it exits. To prevent system damages, it ensures that the selected device is connected only via USB.
