Run specific command while booting

You can write any command that you want to execute while booting in the /etc/rc.local file.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Auto boot
bash /home/ubuntu/scripts/boot.sh > /dev/null 2>&1
# Auto deploy
bash /home/ubuntu/scripts/deploy.sh > /dev/null 2>&1

You can run the following command to check this service status

systemctl status rc.local.service
