man ps
#AIX FORMAT DESCRIPTORS
#       This ps supports AIX format descriptors, which work somewhat like the formatting codes of printf(1) and printf(3).
#       For example, the normal default output can be produced with this: ps -eo "%p %y %x %c".  The NORMAL codes are
#       described in the next section.
