pidof Linux call: https://linux.die.net/man/8/pidof

etc.

You would run the pidof via Qt's QProcess, and read back its output via QProcess::...read..., e.g. https://stackoverflow.com/a/17344946.

Ultimately solutions read & parse what's going on below the /proc pseudo-file system, if you want to do that yourself --- Qt will not have its own function for that.

ich habe jetz so

QProcess process;
    QString pgm("pgrep");
    QStringList args = QStringList() << "firefox";
    process.start(pgm, args);
    process.waitForReadyRead();
    if(!process.readAllStandardOutput().isEmpty())
         qDebug()<<"TRUE";
    else
        qDebug()<<"False";

wie krieg ich jetz noch "oder" um mehrere PIDs gleichzeitig prüfen'?
