CentOS 8 Change Hostname (computer name) command

I am a new CentOS 8 Linux user and setup a server. They setup my server name to ‘li2025-143’ during deployment but now I would like to change the computer name to something else. How can I remove old name and set it to ‘nixcraft-centos8’ on CentOS Enterprise Linux? Can you tell me how do I change the CentOS 8 computer name? How do I assign a static hostname to server running CentOS 8?

5 Ways To Have More Space On Your Hard Drive

Hard drives never have enough space. No matter how much space capacity they offer, it’s just never enough. The reason for that is because it’s very easy to fill up a hard drive. Just take a look at yours. It’s probably about to be filled up. Even worse, it probably is already.

So, what’s filling up you hard drive? If you have no idea what, then why don’t you find out. Here’s an easy way for you to do it.

You can find the biggest individual files on your hard drive by opening File Explorer (Windows Explorer in previous versions) and typing ‘size:gigantic’ into the search bar.

This will bring up a list of any file over 128MB in size, which you can then look through to find large files such as downloads, outdated drivers, backups and ISO images.

Now, that you know what’s filling up your hard drive, it’s time to do something about it. Here are 4 ways to have more space on your hard drive.

Make use of the Windows Disk Clean-up.

Windows has several built-in tools which will automatically find and delete unnecessary files to free up disk space.

The first to try is Disk Clean-up.

1. Search for Disk Clean-up in the Start menu.
2. Wait for it to scan your computer
3. Tick the boxes to delete some or all of the files.
4. Click OK

You have to click the Clean up system files button to do a deeper scan (you have to select the particular drive – usually C: – to check for system files). This will let you delete old versions of Windows which could be using up scores of gigabytes.

Remove games and apps that you no longer need. These take up a lot of space in your hard drive.

A relatively quick and easy way to free up space is to uninstall programs you don’t need or use.

1. From the Start menu click the cog icon to open Settings
2. Click on Apps & features
3. User the Sort by: menu to choose Size
4. Now you’ll see the programs and games
