KILLING ALL USER PROCESSES 
The common method for killing all of a users processes
 usually involves grepping the users name from 'ps', then
 using awk to get the process id's and submitting them
 to 'kill -9'.
 
 Sys V
 ex:  kill -9 $(ps -fuusername | awk '{ print $2 }' )
 
 BSDish
 ex: kill -9 $(ps -aux |grep username | awk '{ print $2 }' )
 
 The problems with doing this way are that it is slow, and
 more importantly, it doesn't always kill all of the processes
 on the first try.
 
 There is a way to do this that always kills all of the users
 processes the first time, and is very fast:
 
 su - username -c 'kill -9 -1'
