Qt 如何将QProcess的输出定向到文件？,qt,qprocess,Qt,Qprocess,我想将qconf的输出重定向到tmp文件夹中的test_settings.txt。我想到了两种可能性： QProcess procWriteProject; procWriteProject.start("qconf", QStringList() << " -sprj " << projectList[0] << " >> " << "\"/tmp/testing.txt\""); procWriteProject.sta

我想将
qconf
的输出重定向到tmp文件夹中的
test_settings.txt
。我想到了两种可能性：

QProcess procWriteProject;

procWriteProject.start("qconf", QStringList() << " -sprj "
    << projectList[0] << " >> " << "\"/tmp/testing.txt\"");

procWriteProject.start("qconf -sprj " + projectList[0] + " >> "
    + "/tmp/test_settings");

qprocessprocWriteProject；
procWriteProject.start（“qconf”，QStringList（）
QProcess procWriteProject；
procWriteProject.setStandardOutputFile（“/tmp/test_settings.txt”）；
procWriteProject.start（“qconf”，QStringList（））

QProcess procWriteProject;
procWriteProject.setStandardOutputFile("/tmp/test_settings.txt");
procWriteProject.start("qconf", QStringList() << "-sprj" << projectList[0]);
