How can I start a Shell Script using QProcess? The Shell Script has eight different commands in it, some with arguments others without.

I tried to start the Shell Script with (using Ubuntu 11.10):

QProcess *Prozess = new QProcess();
Prozess->setWorkingDirectory(MainDirectory);
Prozess->start("/bin/sh", QStringList() << "Shell.sh");

But this doesn't work, that means nothing happens. How to make it work?

Code is fine. Problem is at run-time.

Either your program can't run /bin/sh for some reason (test if you can run gedit instead?), or the MainDirectory variable has wrong directory path (debug it), or the Shell.sh does not exist in that directory (capitalization mistakes? What about "./Shell.sh"?), or you don't have enough privileges to run or modify target directory/files (are they owned by you?).
