Question { Subex, 3206 }

A process is running for 1000 times.How to kill all processes except one i.e kill 999 processes?


Answer

I think it will work.
U can kill all the process except one as below,
set a=`ps -ef|grep -c "XYZ"`
ps -ef|grep "XYZ"|head -`expr $a - 1`|xargs kill -9


To kill all the instances of that process
ps -ef|grep "XYZ"|xargs kill -9
