I'm not sure how much of the wiki is usable for a beginner, as quite
some stuff there will probably still be for PyQt3.

Note sure what you were looking at but the pages you should look at are:

http://www.riverbankcomputing.com/Docs/PyQt4/html/qprocess.html
http://doc.trolltech.com/4.3/qprocess.html

The problem is that this is not a short script. Untested and not sure
about all the API:

class MyFoo(QObject):
  def startProc:
    self.progress = QProgressDialog()
    self.progress.setLabelText("Executing...")
    self.progress.show()
    self.proc = QProcess()
    connect(self.proc, SIGNAL("finished(int, QProcess::ExitStatus)"), self.procFinished)
    self.start("/usr/bin/sh -c 'ls -l /usr/share/doc '")
  def procFinished(self):
    self.progress.hide()

This should execute an ls -l /usr/share/home and show a progressbar
while that is done.  However you'll probably need to play around a bit
with escaping rules when you want to use pipes in the command.
