qprocess

I'm using Qt and bash over it, need to execute something like: bash: cat file | grep string in Qt: QString cmd = "cat file | grep string"; QProcess *process = new QProcess; process->start(cmd); process->waitForBytesWritten(); process->waitForFinished(); qDebug() << process->readAll(); The problem is in pipe ("|"), and process returs nothing. If there is no ("|"), like "cat file" everything is ok. I tried smth. like "cat file \\| grep string", "cat file \| grep string" but result is the same. If I copy the command and run it in bash everything is ok. QString::toAscii().data() and other

I have a code that uses QProcess like this. int main(int argc, char *argv[]) { int status=0; QProcess pingProcess; QString ba; QString exec = "snmpget"; QStringList params; params << "-v" << "2c" << "-c" << "public" << "10.18.32.52" << ".1.3.6.1.4.1.30966.1.2.1.1.1.5.10"; status=pingProcess.execute(exec, params); pingProcess.close(); } This outputs the following. SNMPv2-SMI::enterprises.30966.1.2.1.1.1.5.10 = STRING: "0.1" I want to take(read) this output as string. I searched for this and I cant find the solution. Thanks in advance. Shf Did you try QByteArray QProcess::readAllStandardOutput()

Do I get a finished signal if I start a QProcess using startDetached()? I'm trying to start a process, but I need to be able to get an event when the process has terminated. No you can't get a signal when you use startDetached because you have no object. startDetached is a static function and when you call it the process is started directly without creating a QProcess object. Therefore, even if there was a signal you would not be able to connect it to anything since you have no object to connect from. If you want a signal you should create a QProcess object and then call start on it. You will

I'm writing a cross-platform C++ program using Qt and I want to package/embed a number of binary executables within the program. The program should be able to execute these binaries at runtime. I figured, I would need QResource and QProcess using start() and the ":/..." notation, but I don't seem to get the process running. Is there anything I am missing? Should it work like this? Does the binary need to be set as executable? Background: I am writing a tool which uses Git and I don't want to require the end-user to install Git manually. (Trying this on Mac OS X, BTW.) Update: I am using the

I thought I was going to get the output from a QProcess using the following code: // Start the process process.start(tr("php-cgi www/test.php"),QIODevice::ReadWrite); // Wait for it to start if(!process.waitForStarted()) return 0; // Continue reading the data until EOF reached QByteArray data; while(process.waitForReadyRead()) data.append(process.readAll()); // Output the data qDebug(data.data()); qDebug("Done!"); What I am expecting is to see the output from the program printed to the debug console, but all I see is: Done! I know that: The program is started fine, because the message at the
