Print a file, skipping the first X lines, in Bash

🖨️ How to Print a File, Skipping the First X Lines in Bash

Are you dealing with a massive file, but only need to print a specific portion of it? 📄🤔 No worries! In this blog post, we'll explore how to print a file in Bash, skipping the first X lines. Whether you want to skip a million lines or just a few, we've got you covered! 💪

The Challenge

Imagine you have a ginormous file, and you only need to see the juicy bits at the end. 🔥 But how do you skip those pesky initial lines without scrolling endlessly or losing your mind? 😫

One option might be to use the cat command, but unfortunately, there is no built-in option to skip a specific number of lines. So, we need to get a little creative with our Bash skills!

The Solution

Fortunately, the genius minds in the Bash community have come up with a handy one-liner to solve this problem! 🌟

To print a file while skipping the first X lines, we'll use a combination of tail and head commands. Here's the magical command:

tail -n +X <file> | head

Let's break it down:

1. tail -n +X <file> - This command prints the file starting from line X and onwards. The -n flag specifies the number of lines to print, and the +X notation tells tail to start from line X.

2. head - This command simply displays the output of the previous tail command, with no further modifications.

By piping the output of tail to head, we effectively skip the first X lines and print the rest. Awesome, right? 🙌

Example

To make things crystal clear, let's see an example. Assume we have a file called my_big_file.txt, and we want to skip the first 1,000,000 lines and print the remainder.

Here's the command we would use:

tail -n +1000000 my_big_file.txt | head

And just like that, you'll be printing only the lines you're interested in! 🎉

Get Creative!

Now that you've learned this handy technique, feel free to get creative and adapt it to fit your needs! You can skip any number of lines by adjusting the value of X in the command. It's like having a superpower for dealing with those massive files! 💥
