macosqtqprocessdscl

Get the current macOS shell using Qt

According to this I can get it using this command:

dscl . -read ~/ UserShell

So, I wrote this code using Qt:

QProcess p;
p.setProcessChannelMode(QProcess::MergedChannels);
p.start("dscl", QStringList() << "." << "-read" << "~/" << "UserShell");
p.waitForFinished();
auto result = QString::fromUtf8(p.readAll());

But, the result is empty. What am I doing wrong? This command works fine in the Terminal app.

Addition #1. This works, but it looks stupid :)

p.start("bash", QStringList() << "-c" << "dscl . -read ~/ UserShell")
Solution

  • I think the only alternative is to expand the ~ yourself. So something like...

    p.start("dscl", QStringList() << "." << "-read" << QDir::homePath() << "UserShell");
