euroflasher_

Euroflasher is a lightweight USB imaging tool for writing ISO files to flash drives. It replaces manual dd usage with a guided terminal-style interface.

install script

Why did i make euroflasher? I used dd a LOT, and I can never seem to remember what the correct command with all the parameters is. So Euro just makes it 10x simpler for me and I thought I'd share my work with others.

Is Euro opensource? I believe that everything should be opensource although its not common nowadays, I decided to upload all the code from the installer to euro itself onto this site so its easy to look at and modify if needed,

install.sh

#!/usr/bin/env bash
set -e

echo "Installing euro..."
curl -fsSL https://eurochet.com/euro -o /usr/local/bin/euro
chmod +x /usr/local/bin/euro
echo
echo "Installation complete!"
echo
echo "Run it with:"
echo "    sudo euro"

(all this script does is grab the euro file from my website and put it into /usr/local/bin/)

    echo "euro needs sudo to work properly."
