Options of the ‘ps’ utility

Question

Can someone please enlighten on what the difference is when passing the 'j' and '-l -y' options to the 'ps' utility.

An other good 'ps' resource is welcome too.

Answer 1

The ultimate resource would be the ps man page. You can access this from your terminal as well by typing man ps.

As for the options:

-j 	jobs format
-l  	long format
-y  	Do not show flags; show rss in place of addr. This option can
    	only be used with -l.

output of each switch (other combinations are possible):

[john@awesome]$ps -j
PID  PGID   SID TTY          TIME CMD
30693 30693 30693 pts/1    00:00:00 bash
30879 30879 30693 pts/1    00:00:00 ps

[john@awesome]$ps -l
