meaning of this ps aux output

Question

I was not sure if I am running named. So I did the following:

$ ps aux | grep named  
root      6613  0.0  0.0  13588   920 pts/2    S+ 23:12   0:00 grep --color=auto named

what this output exactly means?

Answer 1

This means that no named process was running. The reason why grep shows up is because it was executing while ps was started. To add headers, and avoid adding grep to the output, use:

$ ps u -C named
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

As you can see, I do not have named running. You can add the h option to hide this header as in:

$ ps uh -C named
