from man page of ps :
STANDARD FORMAT SPECIFIERS
These may be used to control both output format and sorting.
For example: ps -eo pid,user,args --sort user
CODE HEADER
...........................
..........................
start_stack STACKP
start_time START
stat STAT
state S---------------------here is our state.
stime STIME
suid SUID
............................
...........................
and also from same page :
PROCESS STATE CODES
D uninterruptible sleep (usually IO)
R runnable (on run queue)
S sleeping
T traced or stopped
Z a defunct ("zombie") process
For BSD formats and when the "stat" keyword is used, additional letters may be
displayed:
W has no resident pages
< high-priority process
N low-priority task
L has pages locked into memory (for real-time and custom IO)
so thats it, this is the state of the process......
