This command is only readable to a shell, while QProcess works like exec() function --- it starts some program with given arguments.

Try:

Code:

---

pross->clearArguments();
pross->addArgument( "/bin/sh" );
pross->addArgument( "-c" );
pross->addArgument( "df -h | sed '1d' | awk '{print $5\"\\t\"$6\"\\t\"$2}'" );
if( ! pross->start() ) {
   std::cerr << "Error pross. start ;-(" << std::endl;
}
