If you need to execute a BASH script, the most naive way could be

QProcess::execute("/bin/bash", {"-c", "<your-script>"});

If you need to execute single command, BASH is not needed:

QProcess::execute("/path/to/command", {"arg1", "arg2"});

If your command and arguments are hard-coded, this can be used:

QProcess::execute("/path/to/command 'arg1' 'arg2'");

Check QProcess API docs for more advanced use.

I did it recently in python (I don't know C). There are extracts from the code here: https://together.jolla.com/question/191655/error-passing-argument-to-pyotherside/

That worked fine for issuing a command and returning the response.

It turned out that maintaining an SSH session, which meant continuing the shell session, was more complicated; I ended up using pexpect.

You can add simple header file in your app like in my app: https://github.com/Rikujolla/trafficviewer/blob/master/src/forceupdater.h Then you can call it from your qml file

In case you're at this currently: It would actually be cool if you built a generic app for commands, i.e. an app that doesn't anything else then executing the commands a user puts into a textarea in its settings. Virtually the equivalent of a bash script that can be started graphically by clicking the icon.
