- How to view and refresh DNS cache on Linux
- Flushing your local DNS cache can resolve HTTP errors and protect you from DNS spoofing. Here's how to do it on Linux. When you visit a website using a domain name, your system sends a request to the DNS server to obtain the IP address of the domain. This domain IP address pair is saved in the DNS cache for later use, so you don't have to send a request to the DNS server every time to establish a connection. But sometimes, the local DNS cache gets corrupted and causes HTTP errors. Fortunately, flushing and rebuilding the DNS cache on a Linux computer is very simple. Here's how it's done. Why flush DNS cache on Linux? There are several reasons why you might want to rebuild the DNS cache stored on your system. Maybe you have had one

- Enable fractional scaling in Fedora using GNOME
- (FractionalScaling) Fractional Scaling is a handy feature that allows you to maximize optimization for HiDPI monitors and high-resolution laptops. By fine-tuning the scaling, you can create a well-balanced desktop display that's neither too big nor too small and looks great. Although resolution settings are also available, due to operating system limitations, they usually match your actual situation. Additionally, it allows you to increase the size of text and other UI elements on the display without making everything appear blurry. This is useful if you have a high-resolution monitor and want to make text easier to read. Ubuntu20.04LTS introduces 100%, 125%, 150%, 175% and 200% in 2020

- Five Little-Known Modern Bash Scripting Techniques
- Programmers often use the Bash command language to create shell scripts to automate manual tasks. For example, they create Bash scripts for various configurations, file operations, generating build results, and various DevOps-related activities. Almost all Unix-like or Unix-based operating systems provide users with a pre-installed Bash interpreter, so we can use Bash to write more portable automation scripts. As we already know, Bash scripting refers to writing a series of commands using the syntax of the Bash command language, built-in Bash commands, and core operating system CLI programs such as GNU Core Tools. A standard and old-fashioned Bash script usually executes some commands and displays plain text on the terminal

- Seven Tips for Organizing Linux Files and Cleaning Up Your Computer
- On Linux, files not only refer to regular files, but also include directories, pipes, network sockets, devices, etc. In fact, "everything is a file" is a common principle on Linux. If used without control, files can clutter your system and reduce productivity. To improve your workflow and make browsing your computer easier, it's important to organize your files correctly and be consistent and decisive when organizing them. 1. Give files meaningful names Give your files and directories descriptive and meaningful names that reflect their content or purpose. This makes it easier to guess the contents of future folders or files. Remember that Linux is case sensitive, so the directories linuxmi and linuxmi are different, even if they have the same name
