qt中调用shell脚本并监控返回的方法

在QT中经常要调用外部命令或者是执行shell脚本，并且要对执行结果进行分析。

QProcess runShellProcess =new QProcess(this);

//调用过程输出的监控
    connect(runShellProcess, SIGNAL(readyRead()), this, SLOT(readProcess()));
    connect(runShellProcess, SIGNAL(finished(int)), this, SLOT(finishedProcess()));

然后在readProcess()和finishedProcess()中进行分析

void MainWindow::executeShellQProcess(const char *shell){
    shellOutput="";
    runShellProcess->start(shell);
}

void MainWindow::readProcess(){
    QString output=runShellProcess->readAll();
     shellOutput+=output;
     //do something
}

void MainWindow::finishedProcess(){
    qDebug()<<shellOutput;
     //do something
}
