Building a plugin and I am stuck at the executing a shell command, which makes no sense why is not working

Been banging my head trying to understand how building a plugin works, and I tell you is hard and that is because the documentation is old and not relevant anymore.

Now I finally managed to get to the point where i actually need to execute some shell commands from the rpc file, yet the command that works well in cli refuses to be executed by rpc.

So to give an example:

I have a script in ~/scripts/myscript.sh
This script has a method in it names runTest that accepts one argument.

Running this command from terminal like this and works:

source ~/scripts/myscript.sh && runtTest "blabla"

Now if I try to run this command from rpc with the following code:

$cmd = 'source ~/scripts/myscript.sh && runtTest "blabla"';
$process = new \OMV\System\Process($cmd);
$process->execute();But every darn time I get this error: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; source ~/scripts/myscript.sh && runtTest "blabla"' with exit code '127':

Any suggestions ?

What documenation are you looking at? This guide should still work for most things - https://github.com/skyajal/diypluginguide3.x

Was talking about this one DIY Plugin Development

Didn't know about the other one as this is the one always first in all searches :))

As for the ~ it is used for the root directory.

I wanted to reuse some scripts that I already use and they have more than one method in them, but I expected to be able to execute scripts the same way I execute them in the terminal this is the part I don't get, terminal command works fine rpc command returns error...

Well I managed to make any script work, it just took me a bit to realise how to make it work.

Step 1, In your mkconf make a script file (my_script):

#!/bin/sh


set -e
VARIABLE_NAME=$1




. /etc/default/openmediavault
. /usr/share/openmediavault/scripts/helper-functions


source /root/scripts/myscript.sh && runtTest VARIABLE_NAME


exit 0

Step 2 make script executable

chmod +x my_script

Step 3 run script from your rpc

$cmd = new \OMV\System\Process("omv-mkconf", "my_script", escapeshellarg($params['argument_to_pass']) );
        $cmd->setRedirect2to1();
        $cmd->execute();

Works like a charm :)) no I just created the first part of my theme changing plugin using the already built tool, so you can run it either via ssh or via the admin gui.

If user are interested I can make some time and update the current tutorial on the forum on how to build a basic example plugin.
