Quoted from here.
gdb puts the debugged process in its own pgrp and sets the terminal to that pgrp. (Try e.g. ps j on the PIDs of gdb and your program being debugged.)
And what does it mean by
ps j on the PIDs of gdb and your program being debugged
does that mean ps j PID
?
I don't get anything special from this though...
Basically I don't understand what that article is talking about,can anyone explain it in more great details?
