guy i need a help to write bash script to kill program. we are running jboss nodes, when i run ps -e|grep java then it show all running jave node with pid as 1234 java_n1 (this can be run java_n1,n2,n3...nn),

i want write script to identify how many nodes are running and kill them one by one using their pid number as "kill -9 1234". after kill them all need to check whether there are still java nodes are running, if not start previous available nodes after few seconds, ex- before kill the java process there was 10 node, after kill we have to start same 10 nodes.

please help me to write this.

And what have you got so far? We are happy to help, but not to do the work for you.

May I start though by suggesting you have a look at the pgrep command.
