| Hi Rajesh
Sure I will help. But just onerequest, if you have any query in Linux, you can raise it to my forum:
http://www.shankysportal.com/forum
We can identify the Zombieprocess using its stat as “Z”. So I have written a little script as below
#!/usr/bin/ksh
#find the zombie process
ps aux|grep Z
# to get the process id
getPID=$(ps aux|awk '$8=="Z" {print $0}'|tr -s " "":"|cut -d ":" -f 2)
print "The process Id of Zombie process : $getPID";
But it gives only the processId. Now I need more info on requirement from you.
If you want this as alert to urmailbox, it can be done.
Please reply for further help.

| Hi Rajesh
Try this and let me know:
#!/usr/bin/ksh
#find the zombie process
ps aux|awk '$8=="Z" {print $0}'>zombieMail.txt
# to get the process id
getPID=$(ps aux|awk '$8=="Z" {print $0}'|tr -s " "":"|cut -d ":" -f 2)
print "The process Id of Zombie process : $getPID";
#send this info to a mailbox
mail -s 'All zombie process list' [url=mailto:[email protected][color=#0000ff][email protected]<zombieMail.txt[/url]
