ps aux | grep somethinghere.
The output shows the
grep somethinghere as a running process.
My question is, shouldn't
ps aux finish first, then
grep somethinghere run on its output? Maybe there is no need for
ps to finish (there is a pipe between them), but it should run as the first process, while
grep isn't running.
The output means that
grep is ran before
How is this? Shouldn't
ps run first, because its output should be piped to
Even if they are ran at the same time, why is that I always see
grep in output? Shouldn't I not see
grep sometimes, too?
