How to find out and kill all processes for a user?

Hi!

We are using AIX 5.3.

Can anyone please guide me to find out all the running processes for a specific user, say ' admin' and also kill them by force.

Thanks!

ps -ef | grep usernameshows you the running processes
su - username and than kill -9 -1 kills them forced and brings you back to root. Obviously not a good idea to do this for root Smilie

Code:
ps -ef | grep admin | awk '{ print $2 }' | xargs kill -9

or

Code:
kill -9 $( ps -ef | grep admin | awk '{ print $2 }' )

Unless you are trying to shut down a system after a serious hardware problem there is never a reason to issue kill -9 to processes attached to a database.
Use the proper kill signals for your database engine and give the database engine time to respond.

When cleaning idle sessions follow the kill signals defined by your database engine in the correct order and give the database engine time to respond.

Obviously no problem issuing "kill -9" to orphan processes which have no database files open.

The below command is also useful ,

# kill -9 `ps -fu admin |awk '{ print $2 }'|grep -v PID`

Another version of the same script this one with while loop
Code:
USER=name_of_your_ser
ps -ef |grep $USER|while read n1 n2 n3; do kill -9 $n2; done
