System Command QProcess

[jd]

Hello folks,

I'll execute a system command on a Linux maschine. I've created this in a QProcess, but the result was very small.

QString cmd("dpkg");
 
    QProcess* process = new QProcess(this);
    process->start(QFile::encodeName(cmd).data(), QStringList() << "-l" << "| grep" << "xorg");
    process->waitForFinished();
 
    QString tmp = process->readAll();
    qDebug() << tmp;

QString cmd("dpkg");

    QProcess* process = new QProcess(this);
    process->start(QFile::encodeName(cmd).data(), QStringList() << "-l" << "| grep" << "xorg");
    process->waitForFinished();

    QString tmp = process->readAll();
    qDebug() << tmp;

To copy to clipboard, switch view to plain text mode 

The return has a length from one line. This is wrong if I type dpgk -l | grep xorg I becomes over 20 Lines.

If I try this:

process->start(QFile::encodeName(cmd).data(), QStringList() << "-l");

process->start(QFile::encodeName(cmd).data(), QStringList() << "-l");

To copy to clipboard, switch view to plain text mode 

So, with one argument all works fine, if I had more as one argument, the result ist not correctly.


Can someone tell me how to fix the argument list?

Thanks.

so long
