How to Setup ZSH and Oh-my-zsh on Linux

This is my personal setup and configurations

This is my personal setup and configurations for Oh-My-Zsh.

Installation

Step #1 | Dependencies

sudo apt install zsh curl wget git

Step #2 | Install Oh-My-Zsh

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Step #3 | Install themes Powerlevel10k

Powerlevel10k is a collection of terminal themes

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

Open ~/zshrc and find the line that has ZSH_THEME variable and replace it with the following

Set ZSH_THEME="powerlevel10k/powerlevel10k"

Here is my ~/.zshrc file

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
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

# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH

# Path to your oh-my-zsh installation.
export ZSH="$HOME/.oh-my-zsh"

# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="powerlevel10k/powerlevel10k"

# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load
# a theme from this variable instead of looking in $ZSH/themes/
# If set to an empty array, this variable will have no effect.
# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

# Uncomment the following line to use case-sensitive completion.
# CASE_SENSITIVE="true"

# Uncomment the following line to use hyphen-insensitive completion.
# Case-sensitive completion must be off. _ and - will be interchangeable.
# HYPHEN_INSENSITIVE="true"

# Uncomment one of the following lines to change the auto-update behavior
# zstyle ':omz:update' mode disabled  # disable automatic updates
# zstyle ':omz:update' mode auto      # update automatically without asking
# zstyle ':omz:update' mode reminder  # just remind me to update when it's time

# Uncomment the following line to change how often to auto-update (in days).
# zstyle ':omz:update' frequency 13

# Uncomment the following line if pasting URLs and other text is messed up.
# DISABLE_MAGIC_FUNCTIONS="true"

# Uncomment the following line to disable colors in ls.
# DISABLE_LS_COLORS="true"

# Uncomment the following line to disable auto-setting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment the following line to enable command auto-correction.
# ENABLE_CORRECTION="true"

# Uncomment the following line to display red dots whilst waiting for completion.
# You can also set it to another string to have that shown instead of the default red dots.
# e.g. COMPLETION_WAITING_DOTS="%F{yellow}waiting...%f"
# Caution: this setting can cause issues with multiline prompts in zsh < 5.7.1 (see #5765)
# COMPLETION_WAITING_DOTS="true"

# Uncomment the following line if you want to disable marking untracked files
# under VCS as dirty. This makes repository status check for large repositories
# much, much faster.
# DISABLE_UNTRACKED_FILES_DIRTY="true"

# Uncomment the following line if you want to change the command execution time
# stamp shown in the history command output.
# You can set one of the optional three formats:
# "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
# or set a custom format using the strftime function format specifications,
# see 'man strftime' for details.
# HIST_STAMPS="mm/dd/yyyy"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load?
# Standard plugins can be found in $ZSH/plugins/
# Custom plugins may be added to $ZSH_CUSTOM/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git colored-man-pages screen zsh-autosuggestions zsh-syntax-highlighting rbenv ruby)


source $ZSH/oh-my-zsh.sh

# User configuration

# export MANPATH="/usr/local/man:$MANPATH"

# You may need to manually set your language environment
# export LANG=en_US.UTF-8

# Preferred editor for local and remote sessions
# if [[ -n $SSH_CONNECTION ]]; then
#   export EDITOR='vim'
# else
#   export EDITOR='mvim'
# fi

# Compilation flags

# Set personal aliases, overriding those provided by oh-my-zsh libs,
# plugins, and themes. Aliases can be placed here, though oh-my-zsh
# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases, run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

# To customize prompt, run `p10k configure` or edit ~/.p10k.zsh.
[[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh

# My aliases 
alias ls='colorls --sd'

# My Exports
export WL=/rt/wordlists
export SECLST=$WL/
export SECLSTWC=$SECLST/Discovery/Web-Content
export SECLSTDNS=$SECLST/Discovery/DNS

Step 4 | Install Plugins

I will install the following plugins

  • zsh-syntax-highlighting

  • zsh-autosuggestions

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

Step 5 | Tune the prompt

The p10k configurations are stored at the following path

~/.p10k.zsh

Open this file and tune yours like showing the username in the prompt, or ip or any other context. Here is mine

# Generated by Powerlevel10k configuration wizard on 2020-11-24 at 14:55 +03.
# Based on romkatv/powerlevel10k/config/p10k-classic.zsh, checksum 39417.
# Wizard options: nerdfont-complete + powerline, small icons, classic, unicode, dark,

  # hide a tool, it gets shown.
  #
  # Special note on the difference between POWERLEVEL9K_ASDF_SOURCES and
  # POWERLEVEL9K_ASDF_PROMPT_ALWAYS_SHOW. Consider the effect of the following commands:
  #
  #   asdf local  python 3.8.1
  #   asdf global python 3.8.1
  #
  # After running both commands the current python version is 3.8.1 and its source is "local" as
  # it takes precedence over "global". If POWERLEVEL9K_ASDF_PROMPT_ALWAYS_SHOW is set to false,
  # it'll hide python version in this case because 3.8.1 is the same as the global version.
  # POWERLEVEL9K_ASDF_SOURCES will hide python version only if the value of this parameter doesn't
  # contain "local".

  # Hide tool versions that don't come from one of these sources.

  #
  # - shell   `asdf current` says "set by ASDF_${TOOL}_VERSION environment variable"
  # - local   `asdf current` says "set by /some/not/home/directory/file"
  # - global  `asdf current` says "set by /home/username/file"

  # Note: If this parameter is set to (shell local global), it won't hide tools.

  #
  # Note: If this parameter is set to empty value, it won't hide tools.
  # Note: SHOW_ON_UPGLOB isn't specific to asdf. It works with all prompt segments.
