Ubuntu ZSH

Install ZSH (Z Shell), PowerLevel10K, zsh-syntax-highlighting, zsh-autosuggestions and command-not-found plugins on Ubuntu

Installation

Install git:

 sudo apt install git

Install zsh and switch from bash to zsh:

 sudo apt install zsh
 chsh -s $(which zsh)

Install zsh-autosuggestions:

 git clone https://github.com/zsh-users/zsh-autosuggestions ~/.zsh/zsh-autosuggestions
 echo 'source ~/.zsh/zsh-autosuggestions/zsh-autosuggestions.zsh' >>~/.zshrc

Install zsh-syntax-highlighting:

 git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
 echo 'source ~/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh' >>~/.zshrc

Install powerlevel10k:

 git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
 echo 'source ~/powerlevel10k/powerlevel10k.zsh-theme' >>~/.zshrc

Uninstallation

Uninstall powerlevel10k:

1. Remove all references to "p10k" from ~/.zshrc. You might have this snippet at the top:

   if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
     source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
   fi

   And this at the bottom:

   [[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

   These are added by the configuration wizard. Remove them.

2. Remove all references to "powerlevel10k" from ~/.zshrc, ~/.zpreztorc and ~/.zimrc (some of these files may be missing -- this is normal). These references have been added manually by yourself when installing Powerlevel10k. Refer to the installation instructions if you need a reminder.

3. Verify that all references to "p10k" and "powerlevel10k" are gone from ~/.zshrc, ~/.zpreztorc and ~/.zimrc.

   grep -E 'p10k|powerlevel10k' ~/.zshrc ~/.zpreztorc ~/.zimrc 2>/dev/null

   If this command produces output, there are still references to "p10k" or "powerlevel10k". You need to remove them.

4. Delete Powerlevel10k configuration file. This file is created by the configuration wizard and may contain manual edits by yourself.

   rm -f ~/.p10k.zsh

5. Delete Powerlevel10k source files. These files have been downloaded when you've installed Powerlevel10k.

   rm -rf ~/powerlevel10k

6. Restart Zsh. Do not use source ~/.zshrc.

7. Delete Powerlevel10k cache files.

   rm -rf -- "${XDG_CACHE_HOME:-$HOME/.cache}"/p10k-*(N) "${XDG_CACHE_HOME:-$HOME/.cache}"/gitstatus
