README.md

Rainbow shell logo

Displays a logo with your username in rainbow colours every time you open a new terminal window.

Compatibility

Should work with Bash and ZSH on MacOS / Linux.

Requirements

• Lolcat

Installation

1. Download the .asciilogo file and place it in your home directory ¹.
2. Open your existing shell configuration ~/.zshrc, ~/.bashrc (Linux) or ~/.bash_profile (MacOS) in a code/text editor.
3. Place the displayLine and printLogo functions somewhere before the end of your configuration.
4. Place the printLogo $HOME/.zshlogo | lolcat ² line at the end of your configuration where you want the logo to be printed.
5. Save and restart your terminal

You should now see a colourful 🌈 logo with your username printed on the side.

¹ Press Command + Shift + . (MacOS) or Control + Shift + h (Ubuntu) to display hidden dot files on your system.

² If you decided to put the logo somewhere else, replace the $HOME/.asciilogo with the location and name of your logo.

Text replacements

If you want the logo to display other dynamic content, you can expand the displayLine function by piping more SEDs in a row and adding more {{stuff}} to your logo:

echo $1 | sed -e "s+{{username}}+@$USER+g" | sed -e "s+{{something}}+@$REPLACEMENT+g"

Note that $USER is a global variable and prints out your current username. The $REPLACEMENT in this example would contain whatever you want the {{something}} to be replaced with:

$REPLACEMENT=Content you want to display

This should be placed somewhere at the beginning of your configuration file.
