Hostname in Linux

It lists the name of the server. We can change hostname of the server in 2 ways:

1) Permanent Change:
  • Go to the file located in /etc/hostname (We have to edit the hostname in this file)
       # vi /etc/hostname
  • Provide the name whichever you want the hostname and save the file and exit from the file.
  • After performing this please restart the system. The command to restart the system is
       # init 6
2) Temporary Change
   # hostname <name>
Exit and login the server. It will rename your hostname

Developers regularly push code changes or create pull requests to collaborate on features and bug fixes. Whenever new code is pushed to the repository, GitHub triggers Jenkins automatically through a webhook. This integration helps start the CI/CD pipeline without manual intervention. Code Checkout Stage in Jenkins The first stage of the pipeline is the checkout process. Jenkins connects to the GitHub repository and pulls the latest version of the source code. ...

What is Linux?

Linux is an Open-Source Operating System based on Unix.  Linux was first introduced by Linus Torvalds.  The main purpose of Linux was to provide free and low-cost Operating System for users. Since Linux is cost-free, so it is conveniently downloadable and used by people.  Linux is open-source, so it is open to use, and developers may also try to improve the Linux operating system’s features.  It’s a multi-use operating system so multiple people may use the model.  Linux can operate on various types of hardware, so Linux is transportable.  Linux is secure, as it offers secure passwords and data encryption.
