See colorful ls output

📌 Check your shell

ps -p $$

Mine is zsh, so I would need to modify .zshrc.

If you're using bash, it would be .bashrc.

📌 Open and modify your shell configuration file

Open the shell configuration file with any text editor you like.

I used vim here.

vim ~/.zshrc

Then, add export CLICOLOR=1.

You can go to insert mode by pressing i, and add that line. When you're done, press esc and type :wq to save and exit.

📌 Then

source ~/.zshrc

Now when you type ls, you'll be able to see colorized output!
