Do we have generic solution get process start time in AIX & Linux

I wish to get the process start time on AiX and Linux using the same command / script.

I'm able to get the process start time in Linux using the below command:

Code:
cat /proc/<pid>/stat | grep Modify

The same does not work for AiX 6.1 systems.

Can you please let me know the command to get the start time for a process which works on both RedHat Linux 7.1 and AiX 6.1.

Please run the same command on both systems (AIX and Linux):

cat /proc/<your_test_pid>/stat

and post back some sample output.

stat file does not exists on AiX. There is a file called status but it is seems encrypted.

See below:

Code:
ls -ltr /proc/15598024/stat
/proc/15598024/stat not found
$>ls -ltr /proc/15598024/stat
/proc/15598024/stat not found
$>cat /proc/15598024/status

"See below" (in your post above) is not really helpful for at least two reasons:
  1. You do not specific which lines are from which OS. Why omit this critical information? You just want all readers to guess? I asked for output from both servers. Did you provide that?
  2. You use the same PID on both servers.? How can that be correct? I am 99% sure the same exact PIDs do not exist on both servers at the same time. Ah.. you only provided HALF of what I asked for.

Why did you not reply to my question fully and accurately?

Please provide full, accurate, information to those whom who are seeking help.

Thanks.

The following Posix options are available on many OS:
Code:
ps -p <pid> -o stime=

But the format of stime is not standardized.
Better is the elapsed time
Code:
ps -p <pid> -o etime=

where the format is
Code:
[[d-]hh:]mm:ss

Note: the =header extension sets a custom header, and no header if empty (just =).
