Unable to start linux process by Qt

[karankumar1609]

I have chnaged my code below

QScopedPointer<QProcess> my_process(new QProcess());
 
    QString source = parent_path;
    source.append(QDir::separator());
    // source.append("*");
 
    QString destination = map_path;
    destination.append(QDir::separator());
 
    qDebug() << "Source : " << source;
    qDebug() << "Destination : " << destination;
 
    QStringList arguments;
    arguments << "-rf"
    << source
    << destination;
    my_process->start("cp", arguments);
 
    qDebug() << "Copied : " << my_process->waitForFinished();
    qDebug() << my_process->errorString();

QScopedPointer<QProcess> my_process(new QProcess());
     
    QString source = parent_path;
    source.append(QDir::separator());
    // source.append("*");
     
    QString destination = map_path;
    destination.append(QDir::separator());
     
    qDebug() << "Source : " << source;
    qDebug() << "Destination : " << destination;
     
    QStringList arguments;
    arguments << "-rf"
    << source
    << destination;
    my_process->start("cp", arguments);
     
    qDebug() << "Copied : " << my_process->waitForFinished();
    qDebug() << my_process->errorString();

To copy to clipboard, switch view to plain text mode 

Now it makes the data Directory in the destination directory.

Source = "/home/DATA/"
Destination = "/home/DATA_MAP/"

now it creates the DATA folder in my DATA_MAP folder.
I just want my data content in my DATA_MAP directory

Added after 12 minutes:

"parent_path" is the absolute path.

Following code wors for me

{
        QDir dir(parent_path);
 
        QStringList dirs = dir.entryList(QDir::Dirs | QDir::NoSymLinks | QDir::NoDotAndDotDot);

            QString source = parent_path;
            source.append(QDir::separator());
            source.append(directory);
            qDebug() << "Source : " << source;
 
            QString destination = map_path;
