Piping (or command chaining) with QProcess

Question

I\'m using Qt and bash over it, need to execute something like:

bash: cat file | grep string

in Qt:

QString cmd = \"cat fil         


        

Answer 1

The problem is you cannot run a system command with QProcess, but only a single process. So the workaround will be to pass your command as an argument to bash:

process.start("bash", QStringList() << "-c" << "cat file | grep string");
