Introduction
When working with files in Linux, it's essential to be able to quickly peek at the beginning or the end of a file. That's where the trusty head and tail commands come to the rescue! These handy commands allow you to view a snippet of a file without having to open the entire thing. Let's dive in and discover how these commands can make your Linux adventures a whole lot easier.
Head Command - A Glimpse into the Beginning
The head command lets you take a peek at the starting lines of a file. Whether you're curious about the first few lines of a text document or want to examine the initial bytes of a binary file, head has got you covered.
Usage: To use head, simply type "head" followed by the name of the file you want to explore. By default, it displays the first ten lines of the file. However, you can customize the number of lines or bytes displayed by using the appropriate options.
Example 1: Let's say you have a file called "example.txt," and you want to see the first 5 lines of its content. Just type:
[root@192 Desktop]# head -5 example.txt
By executing this command, you will see the first five lines of the "example.txt" file right in your terminal. It's a fantastic way to quickly glance at the initial portion of your file without the need to open it entirely.
Exploring the Tail Command in Linux
Have you ever found yourself curious about the end of a file without scrolling through the entire content? The tail command in Linux is here to save the day! With just a simple command, you can catch a glimpse of the final lines of a file. Let's dive into the world of the tail command and discover how it can add convenience to your Linux journey.
The tail command enables you to view the tail end of a file effortlessly. It's like fast-forwarding to the final scenes of a movie to catch the thrilling conclusion. Whether you're monitoring log files or simply curious about the last portion of a text or binary file, the tail command has your back.
Let's say you have a file called "example.txt," and you want to see the last two lines of its content. Simply enter the following command:
[root@192 Desktop]# tail -2 example.txt
Executing this command will display the last two lines of the "example.txt" file in your terminal. It's a convenient way to quickly catch a glimpse of the final portion of your file without scrolling through the entire document.
