I am making a QT mobile app (Sailfish Os, it's made with Linux) and I need to run some processes with commands which could be run only with command line/terminal. Can I do this using QT/C++ code or I am talking about something impossible? :)
Yes it's possible, you can run Linux commands in Qt app by using QProcess. This is a small example:
QProcess *system_command = new QProcess();
system_command->start("/bin/bash");
system_command->waitForFinished(500);
system_command->write("ls -a\n");
