ps Sort Keys, Format descriptors and Env Variables
Options for the Process Status command.
SORT KEYS
Values used in sorting are the internal values ps uses (not `cooked' values).
If you want to sort by a `cooked' value pipe the output into sort .
c cmd simple name of executable
C cmdline full command line
f flags flags as in long format F field
g pgrp process group ID
G tpgid controlling tty process group ID
j cutime cumulative user time
J cstime cumulative system time
k utime user time
K stime system time
m min_flt number of minor page faults
M maj_flt number of major page faults
n cmin_flt cumulative minor page faults
N cmaj_flt cumulative major page faults
o session session ID
p pid process ID
P ppid parent process ID
r rss resident set size
R resident resident pages
s size memory size in kilobytes
S share amount of shared pages
t tty the minor device number of tty
T start_time time process was started
U uid user ID number
u user user name
v vsize total VM size in bytes
y priority kernel scheduling priority
AIX FORMAT DESCRIPTORS
This ps supports AIX format descriptors, which work somewhat
like the formatting codes of printf.
For example, the normal default output can be produced
with this: ps -eo "%p %y %x %c"
CODE NORMAL HEADER
%C pcpu %CPU
%G group GROUP
%P ppid PPID
%U user USER
%a args COMMAND
%c comm COMMAND
%g rgroup RGROUP
%n nice NI
%p pid PID
%r pgid PGID
%t etime ELAPSED
%u ruser RUSER
%x time TIME
%y tty TTY
%z vsz VSZ
These may be used to control both output format and sort
ing.
For example: ps -eo pid,user,args --sort user

ENVIRONMENT VARIABLES
The following environment variables could affect ps:
COLUMNS Override default display width
LINES Override default display height
PS_PERSONALITY Set to one of posix,old,linux,bsd,sun,digital
CMD_ENV Set to one of posix,old,linux,bsd,sun,digital
I_WANT_A_BROKEN_PS Force obsolete command line interpretation
LC_TIME Date format
PS_FORMAT Default output format override
PS_SYSMAP Default namelist (System.map) location
PS_SYSTEM_MAP Default namelist (System.map) location
POSIXLY_CORRECT Don't find excuses to ignore bad "features"
UNIX95 Don't find excuses to ignore bad "features"
_XPG Cancel CMD_ENV=irix non-standard behavior
In general, it is a bad idea to set these variables. The
two exceptions are CMD_ENV (or PS_PERSONALITY), to set the
desired default personality, and POSIXLY_CORRECT (or
UNIX95), which should be set for Unix98 standard compli
ance.
PS_PERSONALITY Description
none "Do the right thing"

bsd like FreeBSD ps
compaq like Digital Unix ps
debian like the old Debian ps
digital like Digital Unix ps
