Top 5 Courses to Learn Jenkins for DevOps Engineers and Java Programmers

In today's world of Agile and DevOps, Jenkins has become an indispensable tool for both Java programmers and DevOps engineers. Jenkins allows you to set up continuous integration (CI) and continuous deployment (CD) pipeline, which reduces risk on Software development and delivery. This means hassle-free development and deployment. It also means quicker feedback because as soon as a commit has been made into a source control system like Git, Jenkins can start building artifacts and running unit tests. If the build failed due to an issue or if a unit test doesn't pass, you will receive an email instantly. This quick feedback loop ensures that your codebase remains error free.

How to find and kill a Process Listening on a port in Linux? netstat and lsof command examples

In Linux, many times, you want to find out the PID of a process which is listening on a port e.g. if multiple tomcat servers are running on a host and you have to kill that process, but in order to kill that process you need the process id, how do you find the PID of the tomcat listening on port 8080? There are many Linux commands to find the process using a specific port, but I'll share what I use. I always use the netstat command with -p option, which displays process id of the process listening on a port. Btw, netstat is not the only command to find all processes using a particular port, you can also use the lsof command for the same purpose.
