Make use of top 25 commands for Linux OS

The Linux command line is a powerful tool for interacting with your computer. It allows you to enter commands, which are executed by the operating system. These commands can be used to perform various tasks, such as creating and modifying files, navigating the file system, and installing and removing software.

To use the Linux command line, you will need to open a terminal window. This can usually be done by pressing Ctrl+Alt+T or by searching for “terminal” in your application launcher.

Once you have a terminal window open, you can enter commands at the prompt. The prompt is typically displayed as a dollar sign ($) followed by a space, and it indicates that the shell is ready to accept your input.
