[Mr.Floppy]

I gave it a go, but I get an addon error. Looking in the log it says this:

Ah right, you don't want to execute this script in the context of the Kodi process.

Here's a fix... http://sprunge.us/eLXN

Put this alongside the texturecache.py script, call it shell.py and give it execute permissions - on Linux:

Code:

wget http://sprunge.us/eLXN -O ~/.kodi/userdata/shell.py && chmod +x ~/.kodi/userdata/shell.py

Now your Runscript() call needs to be (note this assumes the texturecache.py script is alongside the shell.py script, otherwise specify the full path to texturecache.py - don't use special://whatever):

Code:

RunScript(special://profile/shell.py,./texturecache.py,c)

For instance to map this to a remote control button:

Code:

<red>XBMC.RunScript(special://profile/shell.py,./texturecache.py,c)</red>

As a bonus you'll get notifications on start and finish, and you won't be able to run multiple instances (which wouldn't be good).

@milhouse:

While the solution via the shell.py script is working fine on my KODI Krypton v17.4 installations under LibreELEC on my Raspberry Pi and ANDROID box, I can't get it to work on my PC using KODI for windows...

First problem:
As there are no "/var/run/" directories on the KODI installation on my PC running Windows 7, I replaced the line from
pidfile = "/var/run/shellpy.pid"
to
pidfile = "C:\Users\Stefan\AppData\Roaming\KODI\userdata\shellpy.pid"

-> problem solved

Second problem:
Trying to run the script shell.py throws the following excepton in the KODI log:

I assume that the "WindowsError: [Error 2] Das System kann die angegebene Datei nicht finden" (translated to english: "The system can't find the specified file") is caused by the missing "kodi-send" command under Windows, right?
I was not able to find an alternative command line tool for windows, but maybe I didn't use the appropriate search terms, since I'm a noob regarding python programming...

So - how could I get a "work-around" for this problem?
