Check for running applications in linux using Qt

Yes these tools are always there for me to.

On Windows there is no /proc also.
On the MacOsX is sysctl with is better then parsing /proc (and strictly speaking MacOSX is not Linux it's Unix - question was regarding Linux).

IMHO on Linux I would go with parsing the /proc(fs), safer.

That's right.

I totally agree with you point, but I think it's gonna be hard to implement for topic-starter

IMHO reading /proc is easier, for example (pseudo code, not correct but gives the basic idea):

Read /proc: QFile().open(fileName) -> QByteArray ba = QFile().readAll(); -> parse(ba);
Process: QProcess().start(FileName/command) -> slot ReadyRead() -> QByteArray ba = QProcess().readAll(); -> parse(ba);

Reading /proc don't involve signal/slot mechanism (and, to clarify here, I don't take into account blocking QProcess() because that's just bad programming IMHO, for this problem at least).

And with blocking QPRocess: QProcess().start(command) -> QProcess().waitForFinished() -> QByteArray ba = QProcess().readAll();. Same as reading /proc.

Maybe this will help topic starter to get basic idea about possibilities (practically he already has ready solution).

EDIT:
I forgot actual parsing and with correct command parsing would be reduced to splitting by the new line, so indeed that would be easier to manage/implement .
