Can I ask you to "translate" this to English for me ?
QP->start("/bin/sh", QStringList() << "-c" << command);


Sure: call operator<< on the results of calling some unknown function QStringList() and (char *)"-c" and then call operator<< on the results of that with some unknown object command. Then pass that ojbect and (char *)"/bin/bash" to method start on some unknown object QP. What any of this actually does in not known in the context of what you've presented here. I'm guessing it pulls the tail on a elephant at the Bronx Zoo. Its as valid a guess as anything else.

Assuming this goes back to your question about creating a link between /dev/ttyUSB0 and something that looks might be a bluetooth device file (which you've now helpfully removed, so I can't refer to it .. nice), Are you sure that's what you want to do? This would suggest that you have a serial USB dongle (i.e. an RS232 to USB converter) to which you've attached a serial BlueTooth receiver. I don't know if any such beast actually exists. I suspect not, so you're probably going in the wrong direction here.

But a quick perusal of the docs for QProcess, which is what I assume that QP is, doesn't suggest that QP launches a terminal, so is that part of what command does? Perhaps you'd be better off looking into how to use sudo to let a user launch a given command without having to enter a password? https://askubuntu.com/a/159009 Alternatively, you could change the ownership of the executable to a user with sufficient access to perform whatever task it is you're trying to do, and then set the suid bits on the executable so the executable runs as that user. You man need to call seteuid() and setegid() as well.
Keep Calm and Carry On
