Quoting problem with QProcess

[the_bis]

Hi,
I need help for using QProcess.
I have to run a cmd like this:

cmd -param1 -param2 value2 -param3 value3:title="My Title with spaces"

cmd -param1 -param2 value2 -param3 value3:title="My Title with spaces"

To copy to clipboard, switch view to plain text mode 

For param1 & param2 no problems; param3 dont'work.

My code is:

[...]
#include <qprocess.h>
 
int main (int argc, char **argv)
{
 
[...]
 
  QApplication a (argc, argv);
  QProcess *proc;
 
[...]
 
  proc = new QProcess ();
  proc->addArgument ("cmd");
  proc->addArgument ("-param1");
  proc->addArgument ("-param2");
  proc->addArgument ("value2");
  proc->addArgument ("-param3");
  QString myCmd = "value3:title=\"My Title with spaces\"";
  proc->addArgument (myCmd);
 
  if (!proc->start())
  {
    // error handling
    exit (-1);
  }
 
  return 0;
 
}

[...]
#include <qprocess.h>

int main (int argc, char **argv)
{

[...]

  QApplication a (argc, argv);
  QProcess *proc;

[...]

  proc = new QProcess ();
  proc->addArgument ("cmd");
  proc->addArgument ("-param1");
  proc->addArgument ("-param2");
  proc->addArgument ("value2");
  proc->addArgument ("-param3");
  QString myCmd = "value3:title=\"My Title with spaces\"";
  proc->addArgument (myCmd);

  if (!proc->start())
  {
    // error handling
    exit (-1);
  }
	
  return 0;

}

To copy to clipboard, switch view to plain text mode 

When I launch this program I have no error but the third parameter is not correct. This arrives quoted. I think I have to avoid quoting...
I'm using Linux with bash shell.

Thanks for any help,

Well, if you quote it then it arrives quoted... When using bash (or other shell) you use quotes when you wish to inform the shell that a particular block of text is really a single element although it contains spaces or other special characters. QProcess doesn't use the shell, it invokes the command directly, so quoting is not needed. Try passing simply "value3:title=My Title with spaces" as the third argument.
