Introduction
The Linux command head is a useful tool for viewing the beginning of a file or output. It is a part of the GNU Core Utilities package, which is installed by default on most Linux distributions. The head command allows you to view the first few lines of a file or output, which can be useful for quickly viewing the contents of a file or for debugging purposes. It can also be used to view the beginning of a large file without having to open the entire file.

Linux Command Line Basics
The Linux command line is a text-based interface that allows users to interact with the operating system. It is a powerful tool that can be used to perform a variety of tasks, from basic system administration to complex programming. In this article, we will cover the basics of the Linux command line and how to use it.
Navigating the Command Line
The first step to using the command line is to open a terminal window. This can be done by pressing the “Ctrl + Alt + T” keys on your keyboard. Once the terminal window is open, you will be presented with a prompt. This prompt will usually look something like “user@hostname:~$”. This is where you will enter your commands.
To navigate the file system, you will need to use the “cd” command. This command stands for “change directory” and it allows you to move around the file system. To move to a different directory, you will need to type “cd” followed by the path to the directory you want to move to. For example, if you wanted to move to the “Documents” directory, you would type “cd Documents”.
Listing Files and Directories
Once you have navigated to the directory you want to work in, you can use the “ls” command to list the contents of the directory. This command will list all the files and directories in the current directory. You can also use the “ls -l” command to list the contents in a long format, which will show you more information about each file and directory.
Creating and Deleting Files and Directories
The command line also allows you to create and delete files and directories. To create a file, you can use the “touch” command followed by the name of the file you want to create. To delete a file, you can use the “rm” command followed by the name of the file you want to delete. To create a directory, you can use the “mkdir” command followed by the name of the directory you want to create. To delete a directory, you can use the “rmdir” command followed by the name of the directory you want to delete.
Conclusion
The Linux command line is a powerful tool that can be used to perform a variety of tasks. In this article, we have covered the basics of the Linux command line and how to use it. We have also discussed how to navigate the file system, list files and directories, and create and delete files and directories.
