One side effect is that this pick up "defunct" processes (which display in the old "ps" as uid -3), but they might be interesting anyway.
Avoided outputting the "args" option because it could contain hyphens.

Code:

MMMDD=`date +'%b %e'`
UNIX95= ps -af -o user,pid,ppid,cpu,etime,stime| \
                grep -v "PID"| grep -v "${MMMDD}" | grep "\-"

If you need to output the process line in new "ps" format then we can extend the pipeline to pick up the PID ($2) and feed it to "ps -fp<pid>", eliminate "defunct", and then feed the list to a less-complicated "awk" because all the dates will be in the same format. No need to do "ps -ef" for every individual process.

Afterthought: The UNIX95 "ps" etime field contains the number of days old. This might be simple.

Thank you very much !!

Finally got it working.. added following filters for user procs older 5 days in this case.

Code:

UNIX95= ps -af -o user,pid,ppid,cpu,etime,stime| grep "\-" | awk '$5 >= "5"' |\
awk '{print "ps -fp "$2}'|sh | awk '( NR ==1 ) || ( NR > 1 && $1 !~ "UID")'
