How to get Start Date/Time of a Process in HP-UX

[Alzhy]

Is there a command in HP-UX that can precisely show a process' start date and time?

Thanks.

Hello

ps has the option your looking for.

Cheers

Hi,

Using the lstart specifier of ps shows the start date and time of a process. man ps for more info.

ps

[RAC_1]

ps -l (long listing will show start time/date)

Once the time lapsed is more then 24 hrs. only start date will be shown. Only time is shown if process is less than 24 hrs. old.

man ps gives more details.

Also you can use UNIX94 variable to get required info.

UNIX95= ps -l -o "stime,args"

More precisely,

'ps -ef |grep {processname}'

eg. '

# ps -ef|grep inetd
root 21490 1 0 08:28:16 ? 0:00 /usr/sbin/inetd

or 'ps -ef|grep {pid}' if you know the pid.

eg.

# ps -ef|grep 21490
root 21490 1 0 08:28:16 ? 0:00 /usr/sbin/inetd

Hope it helps

Thank you so far for the replies.. what I am after is some fort if a tool, ie. procinfo which will show Process start DATE and TIME or EPOCH Time is possible.

ie.
Fri Apr 16 07:59:56 PDT 2004
or
1082127596 (in Epoch Time - )

Actually similar to "glance -s" PROC_STARTTIME but I cannot seem to get a command line adviser syntax to give me a result of something like:

root# procinfo.ksh SomeLongRunningApp
PROC STARTTIME: Fri Apr 16 07:59:56 PDT 2004

Hi Nelson,

In my previuos post using the lstart of ps gives the output you are looking for and it does not matter if the process is running for more than 24 hours. You could use this in a script so you can specify what process you want info on.

IDEV:/usr/users/pleddy/scripts>ps -efo cmd,lstart | grep sysl
/usr/sbin/syslog Tue Apr 13 11:16:45 2004
grep sysl Fri Apr 16 16:06:59 2004

Hey Pedro,

ps -efo cmd,lstart | grep sysl

does not work,

even UNIX95=1 ps -efo cmd,lstart | grep sysl

does not work. and man page for ps on HP-UX 11.11 makes no mention of "lstart" as one of the "column formats" on ps..

What UNIX are you on?

[Peter Leddy_1]

Hi Nelson,

I did that on one of our Tru64 boxes and it works fine. Got a bit mixed up there, apologies.

I guess I would just have to reckon this from:

UNIX95=1 ps -efo etime,comm

Thanks for all your replies.....

Hi Nelson, in my old system, if i remember righ, show with command "ps -edalf".

You could write a simple c program and use the pstat call and the pst_status structure to get the start time in epoch.

You can refer to the man page on pstat for more info....

struct __pst_status {
_T_LONG_T pst_idx;/* Index for further pstat() requests */
_T_LONG_T pst_uid; /* Real UID */
_T_LONG_T pst_pid; /* Process ID */
_T_LONG_T pst_ppid; /* Parent process ID */
_T_LONG_T pst_dsize; /* # real pages used for data */
_T_LONG_T pst_tsize; /* # real pages used for text */
_T_LONG_T pst_ssize; /* # real pages used for stack */
_T_LONG_T pst_nice; /* Nice value */
struct __psdev /* TTY of this process; -1/-1 if there isn't one */
pst_term;
_T_LONG_T pst_pgrp; /* Process group of this process */
_T_LONG_T pst_pri; /* priority of process */
_T_LONG_T pst_addr; /* address of process (in memory) */
_T_LONG_T pst_cpu; /* processor utilization for scheduling */
_T_LONG_T pst_utime; /* user time spent executing (in seconds) */
_T_LONG_T pst_stime; /* system time spent executing (in seconds) */
_T_LONG_T pst_start; /* time process started (seconds since epoch) */
.........

Thanks Navin.. bulls eye!

I've no done any C in the last 10 years.. would you mine posting a code that I could compile?

Also, would this structure (or something similar) be accessible in PERL?
