Jack_showtime man page doesn't mention any options available and the problem I have is the frequency of the lines it outputs. Over 12,000 lines per second according to a little Perl script. ($ jack_showtime | perl -w line-counter.pl) I can get to see relevant lines in my program, but it seems to need all of this (j_s is the jack_showtime QProcess): j_s->readAll(); // otherwise old news waitAbit(20); // otherwise blank line QString dirout = j_s->readLine(); // " dirout = j_s->readLine(); // A recent relevant line ui->statusbar->showMessage(dirout, 0); // show it. Has to be a better way. A jack_showtime option to limit its verbosity to n lines per second, would be the nicest, if anyone is around that way, but for now; maybe a script could tame it? Any suggestions appreciated. -- Thanks again, John.
