Run Linux commands from Qt4
c++, linux, posix, qt4, shell
Solution
QProcess p;
p.start( /* whatever your command is, see the doc for param types */ );
p.waitForFinished(-1);
QString p_stdout = p.readAllStandardOutput();
QString p_stderr = p.readAllStandardError();
Problem
How can I run command-line programs under Linux from Qt4? And of course I want to obtain the output in some way I can use. I'd use it for an `ls | grep`, but it's good to know for any future issues.
