Best Shell

Bash is the most common shell and is for most people more than enough but if you want a more modern shell with autocompletion and others useful feature, you can change your shell.

There are 2 really good shell other than bash, Zsh and Fish.

• Zsh is really customizable and is POSIX compliant, it means like bash it can run bash,sh scripts directly in the terminal. If you're willing to get the best terminal, I think its the best of both world. Here is a script install that I recommend:

sh -c "$(curl -fsSL https://raw.githubusercontent.com/romkatv/zsh4humans/v5/install)"

• Fish comes with really great default right out of the box, its a really good option for beginners but also for more advanced users though it's not POSIX compliant, that means you can't run bash directly in the terminal. That is the reason I don't recommend it if you're scripting bash. Although you can still use it along with bash but I dont like to switch between 2 shells. Here is how to install latest Fish on Debian based distros:

sudo apt-add-repository ppa:fish-shell/release-3
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install fish
chsh -s /bin/bash $USER # Optionnal, sets default shell to fish

After installing zsh, if you want to change prompt (for e.g mine below) you can by following these steps:

Custom Prompt

1. Open ~/.p10k.zsh in a text editor

2. Seek for the line with POWERLEVEL9K_LEFT_PROMPT_ELEMENTS

3. You can then add whatever element you want to the list, it will show on the left side of the prompt in the order you specified, here is a list of elements for reference: https://github.com/Powerlevel9k/powerlevel9k/blob/master/README.md#available-prompt-segments

You can also change font-family: https://github.com/romkatv/powerlevel10k?tab=readme-ov-file#manual-font-installation
