I am trying to get a GNU/Linux Bash script to run as soon as a network connection is established on my Raspberry Pi. I tried following the instructions on several pages:

I have tried adding my script to /etc/network/if-up.d and running sudo chmod ugo+x on the file.

I have tried adding the line post-up <path/to/script.sh> to /etc/network/interfaces

I am really quite clueless here.

More info:

The script runs fine when manually run, here it is: http://pastebin.com/UJvt5HYU (I did remove my personal info (email addresses, passwords), but other than that, the script is unchanged. This script also uses the sendEmail program (can be found at http://caspian.dotconf.net/menu/Software/SendEmail/).

  • We cannot help you if you don't show us the relevant files. Please post your script's code. Does it run OK if you run it manually? Are you using a full path or a relative one? Please always include all the relevant files in your question.

  • Can you make the script log to a file so that you can see what the script is trying to do, and what it fails on ? Also, have you tried putting the script into /etc/network/if-up.d but make sure it has no file extension ?

I was able to solve this by putting the script into /etc/network/if-up.d/ with no extension.

I have a .desktop file in ~/.config/autostart that executes a python email script, which looks like this:

[Desktop Entry]
Name=EmailOnBoot
Exec="python ~/Path/To/SendEmail.py"
Type=Application

If you dont have ~/.config/autostart you can just create it, and make the file.desktop in it executable. It executes after everything else including network connection (WiFi in my case).
