Need to list 3 days old processes
Code:
ps -xfu <user name>

this command line will list all the process currently running for <user name>.
I need to filter this output. I need all the process which are running for more than 3 days(excluding demon/sys process) . The list should include PID, PPID, STIME, process/command.

I am using HP-UX machine and I am trying to write a KSH script for this.
Any help will be appreciated.

can you try this ?
Code:
ps -eo pid,ppid,command,stime | grep `perl -MPOSIX -le 'print strftime "%b%d",localtime(time-(3*60*60*24))'`

or

Code:
UNIX95=1 ps -eo pid,ppid,command,stime | grep `perl -MPOSIX -le 'print strftime "%b%d",localtime(time-(3*60*60*24))'`

Thanks @Ygemici. I tried the command line you provided but returned an error -

Code:
ps: command is not a valid field name

/opt/perl5/lib/5.00502 /opt/perl5/lib/site_perl/5.005/PA-RISC1.1 /opt/perl5/lib/site_perl/5.005 .).

Hmm probably your perl version is not support posix module : `Can't locate POSIX.pm in @INC (@INC contains: /opt/perl5/lib/5.00502/PA-RISC1.1`

it says `Can't locate POSIX` so cant found it

Then you must update the Perl Smilie

Also, the command syntax suggested for "ps" is not valid on HP-UX .
Maybe respondant meant?:
Code:
UNIX95=1 ps -eo pid,ppid,comm,stime

However the format of the "stime" column is probably not useful for processing in the suggested Perl program because the field format changes from "HH:MM:SS" to "MMM dD" for processes more than 24 hours old.

thanks @methly additional information
perl program's output is month and day of the past times..
maybe could be space in between
Code:
"%b %d"

i know like this `comm gives little command` and `command param gives full command however now we can get the output (
and for HH:MM:SS format i add something )

Code:
# ps -eo pid,ppid,command,stime | grep -E "$(perl -MPOSIX -le 'print strftime "%b %d",localtime(time-(3*60*60*24))')|$(perl -MPOSIX -le 'print strftime "%b %d",localtime(time-(2*60*60*24))')|[0-9]*:[0-9]*:[0-9]*"
