Simple script to change hostname of raspberry pi
change-hostname-from-boot.sh must be launched at startup. crontab file provided shows the cron way of doing it.
add line @reboot /home/pi/scripts/change-hostname-from-boot.sh to crontab or use provided crontab file
This script reads the file /boot/hostname.txt which is accessible on the bootable raspbian media
Example use: Once the boot script is set up, hostname can also be changed by remotely running the change_hostname script which edits the /boot/hostname.txt file
sh change_hostname.sh [newhostname]
run remotely with ssh user@host 'bash -s [newhostname]' < ./change_hostname.sh
