Execute external Python script

The following article describes how an external Python script located on the control cabinet can be executed directly via horstFX.

The following steps serve as an exemplary approach. Further actions may need to be carried out.

1. Making the Python script executable

To make the created Python script executable, the first step is to find the installation path of Python. This can be done by using the following command in the console:

which python3

Next, the path obtained should be added to the Python script in the top line as the following command:

#!�PFAD�

Replace "PFAD" with the output obtained from the command "which python3". Therefore, the command could look like this:

#!/usr/bin/python3

Next, you can test if the Python script can be started via the console.

If you encounter the error "python linux bad interpreter ^M no such file or directory," it means that the line endings are not interpreted correctly. Unix is looking for ^M in the file or path. This issue can occur when the Python script is created on a Windows PC.

To resolve this, you can make the Python script Unix-compatible by installing dos2unix on the control panel.

To do this, log in as the root user:

su -l root

Please request the password directly from fruitcore.

To install dos2unix:

 apt-get install dos2unix

 dos2unix FILENAME
