I am using Krusader 2.7.2 as a file manager.

When I double click on a Python script, it shows the following error message:

execvp: Exec format error

After I click "Ok" another error message is shown:

Could not start 'file.py'

After I click on "Ok" nothing more happens.

How can I configure Krusader to open my Python scripts in Kate (or KDevelop) rather than try to run them?

  • Easiest method and security wise better: do not make the files executable. use python3 {script} to execute them. When the files are not executable an editor will treat them as text file

In Krusader, you can right-click on a file, then "Open With", then "Other...", and in the menu that opens you can associate the file type with the application you want. Check "Remember application association..." at the bottom so it is persistent.

This will actually associate the MIME type associated to this file to the application system-wide. You should also be able to edit that from the system settings somewhere. I am not sure however how the file type/extension is linked to the MIME type.
