generating the keyboard events in shell script

Hi everyone,
is it possible to generate keyboard event "Ctrl+c" from a shell script code.?

i have written a shell script to compile my application and copy it to the server home directory , inorder to run my application i need to start the server (by running a shell script). but before that i need to stop the the currently running instance of my server. to do that i have to generate a keyboard event (Ctrl+c which i press it manually). i want to automate the entire process by writing a shell script i am able to run the server just by adding ./run.sh in my shell script. but befoe that to stop my server can i generate a keyboard by using a shell script event(ctrL+C) to stop server.?

Yes - ctrl+c is really just a way to send SIGINT, so use "kill -INT <pid>" or "killall -INT <program-name>".

To do that i need to get the pid(processID) of the server , i use netstat -pl(manually) , how do i get the pid of the server instance running through the shell script.?

Thanks for the reply mate.
