An animated ASCII rickroll

This is a fully self-contained ASCII Rickroll! It makes a great error message, or harmless pentesting payload.

It's available in C, Python, and BASH.

BASH!

The shell script contains the first ~25 seconds worth of frames from "Never Gonna Give You Up". They were converted to ASCII images and appended to the end of the script. The script steps through the file printing one frame worth of lines at a time. The first 25 lines of the file are used for code and comments. This means every frame must have a 25 line offset. This is the small version for 130x36 terminal resolution.

Now with sound

The latest addition has MP3 audio embedded into the file! Enjoy the magical notes of Never Gonna Give You Up as your friend asks what you did to their computer! NOTE: Requires ffplay to be installed on the target system.

Installation and usage

Clone the repo!

git clone https://github.com/johnsoupir/ASCII_Rickroll.git

Change directory

cd ASCII_Rickroll/BASH_Rickroll

Execute the Rickroll!

./ASCII_Rickroll.sh

C - NEW! Now with 100% more glorious C!

A fully self-contained ASCII Rickroll written in C!

The C version is available as a library, so you can use it in your own programs!

A ready to use example is included as well.

Installation and usage

Clone the repo!

git clone https://github.com/johnsoupir/ASCII_Rickroll.git

Change directory

cd ASCII_Rickroll/C\ Rickroll

Compile the C program - (You will need GCC and make installed)

make

Execute the Rickroll!

./rickroll

If you'd like to "install" the program so it's available to run from anywhere:

sudo mv ./rickroll /usr/local/bin/rickroll

Include in your own project!

It's as simple as including ASCII_Rickroll.h and calling the function roll()!

#include <stdio.h>
#include "ASCII_Rickroll.h"

int main() 
{
    printf("Hello World!\n"); //Place your code here
    roll(120); //Roll the ASCII Rickroll at 120ms per frame. 
    return 0;
}

Files

• main.c: Example program that uses the library.
• ASCII_Rickroll.c: Contains the implementation of the roll and delay functions.
• ASCII_Rickroll.h: Contains the declaration of functions and the frames array.
• Makefile: The makefile to compile the C program.

Roadmap

I'm working on:

• Python version
• Auto-scaling to terminal size
• Selectable length
• Selectable speed
• Audio support in Python
• Audio support in C
• (Better) Audio support in BASH
• Full C version that takes command line args
