Bash script for creating a bootable usb stick on OS X

26 January 2014

Many times you have to create a bootable usb stick on a mac. I always follow the instructions at How to create a bootable USB stick on OS X. I created a quick bash script that makes this process faster

###!/bin/bash
HELP_STR="please provide location of .iso"
if [ "$#" -lt 1 ]; then
  echo $HELP_STR
else
  echo "`diskutil list`"
  echo "==============="
  echo "enter disk to eject, e.g., /dev/disk1"
  echo -e ">> \c"
  read word
  echo "ejecting: \"$word\""
  diskutil unmountDisk "$word"
  echo "copying "$1" to "$word" note this may take a while and there wont be a progress bar"
  sudo dd if="$1" of="$word" bs=1m
fi
