Auto start application error in Angstrom Beaglebone Black

Creating a service to startup at BeagleBone Black boot time:

Create a shell script such as /usr/bin/myFancyBash.sh:

#!/bin/bash

# this could be any runnable code or shell script, really
/usr/bin/myFancyPython.py
Note that the first line is critical.

Create a service file in /lib/systemd/myFancy.service such as:

[Unit]
Description=My Fancy Service

[Service]
Type=simple
ExecStart=/usr/bin/myFancyBash.sh

[Install]
WantedBy=multi-user.target
Create a symbolic link between your script and a special location under /etc:

ln -s /lib/systemd/myFancy.service /etc/systemd/system/myFancy.service
Make systemd aware of your new service

systemctl daemon-reload
systemctl enable myFancy.service
systemctl start myFancy.service
Reboot the BeagleBone Black to see your script in action

If you wish to control the service at runtime, you can use systemctl commands:

systemctl status myFancy.service
systemctl stop myFancy.service
systemctl start myFancy.service
systemctl disable myFancy.service
