Full Discussion: Time field showing Zero in ps command output
Top Forums Shell Programming and Scripting Time field showing Zero in ps command output Post 302943009 by MadeInGermany on Monday 4th of May 2015 02:54:42 PM

disown builtin is in ksh93. HP-UX 11.31 and older have ksh88.
Workaround is closing or redirecting all the file handles, at minimum stdin(0), stdout(1), stderr(2).
TIME is accumulated CPU usage. Actual CPU usage is PCPU.
You can display all the times with this:
Code:
UNIX95=1 ps -eo pid,user,time,etime,stime,pcpu,args

Average CPU consumption is the quotient (time / etime), (CPU time / Elapsed time).
The stime is an absolute time of the process start, usually less precise than (current_time - etime).
