Find and Kill PID in Fedora

Hi friends...
Following shell script  part will find the process id which process running on a given port (e.g. in my example it's 8080) and kill the process.

x=$(netstat -nap | grep java | grep :8080 | awk '{printf("%s\n", substr($7, 1, index($7, "/") - 1))}')

if [$x eq '']; then
    echo "---> [INFO] --- Application server not running in port 8080..."
else
    kill -9 $x
    echo "---> [INFO] --- Application server running in port 8080 and kill in process #" $x
fi

Hence most of the cases we have to increase PermGen size more than required to deployed applications and it's wasting of memory in the system.  There is a solution for them to release PermGen size and let it clean by GC in JVM at hot deployment. Step 01: Include below dependency to pom.xml <dependency>               <groupId>se.jiderhamn.classloa der-leak-prevention</groupId>         <artifactId>classloader-leak-p revention-servlet</artifactId>   <version>2.2.0</version> </dependency> Step 02: Add listener to web.xml <listener>   <listener-class>se.jiderhamn.c lassloader.leak.prevention.Cla ssLoaderL...
