Sometimes a process comes and goes faster than I can
ps aux, I tried
watch -d -n0.1 "ps aux | tail" but again, that's restricted to 1/10th of a second. What I really want is to run a command and follow all new processes, one per line, as they spawn. Even processes that run fast. I know
strace has abilities similar to this but I haven't been able to get it to do what I want.
tl;dr : is there a way to log all new processes?
I don't want to know much, no more than a line of
ps aux would give me, for the current case I just have a process that's spawned by another and disappears, I want to be able to run it, but I don't know what the command would be. Even knowing new PIDs would be sufficient, since I could figure a script that would take these and run
ps | grep on these and give me more info while the process is running (assuming hopefully the process is still around when
ps gets going)
