Welcome to Part 2 of the Ubuntu home lab setup series. In this section, we’ll focus on making the terminal experience powerful and developer-friendly. We’ll install popular utilities, configure a rich shell environment with Zsh, and set up Neovim and TMUX.
🛠️ Step 1: Install Utilities
Install a collection of essential terminal tools:
sudo apt install -y \
net-tools \
zsh \
bat \
unzip \
ripgrep \
grep \
xclip \
htop \
ranger \
iptables \
fzf
net-tools: A collection of networking tools, which includes some of the popular tools like ifconfig and netstat. They are very handy in managing network interfaces and connections.
zsh: A powerful shell which complements bash functionality with a strong scripting capability and personalisation options.
bat: Better cat with syntax highlighting.
unzip: Utility for unpacking ZIP files.
ripgrep and fzf: Search and fuzzy finding.
grep: Another search tool for searching plain-text data on the command line for lines that match a regular expression
xclip: A command line interface to the X11 clipboard, which can be used to copy and paste text or files. If you install NeoVim, this is a must-have to copy text to and from NeoVim out of the terminal.
htop: Interactive process viewer.
ranger: Console file manager.
iptables: It is a Linux command line utility to manage the Linux kernel firewall. It is implemented within the netfilter framework. We can define rules to either accept a packet or reject it.
🌀 Step 2: Install LazyGit
LazyGit is a simple terminal UI for Git:
LAZYGIT_VERSION=$(curl -s "https://api.github.com/repos/jesseduffield/lazygit/releases/latest" | grep -Po '"tag_name": *"v\K[^"]*')
curl -Lo lazygit.tar.gz \
"https://github.com/jesseduffield/lazygit/releases/download/v${LAZYGIT_VERSION}/lazygit_${LAZYGIT_VERSION}_Linux_x86_64.tar.gz"
tar xf lazygit.tar.gz lazygit
sudo install lazygit -D -t /usr/local/bin/
🎨 Step 3: Install Git-Delta
Git-delta is a syntax-highlighting pager for git, diff, grep, and blame output. It's designed to make developer’s life easier by making reviewing code changes easier and efficient. It improves the readability and layout of diffs:
Download delta from the official page.
Optional: Install a theme configuration file like themes.gitconfig into ~/.config/delta.
Add to ~/.gitconfig:
[core]
pager = delta
[interactive]
diffFilter = delta --color-only
[include]
path = ~/.config/delta/themes.gitconfig
[delta]
features = arctic-fox
navigate = true
line-numbers = true
side-by-side = true
[merge]
conflictstyle = zdiff3
📝 Step 4: Install Neovim
NeoVim is my favourite text editor of choice. Even though I use nano for most steps in this document for convenience. Follow the steps below to install NeoVim.
To get the latest version of Neovim:
sudo add-apt-repository ppa:neovim-ppa/stable
sudo apt update
sudo apt install -y neovim
If you want to configure NeoVim to have support for LSP servers, Fuzzy Finding, Lazy and Mason Plugin support, Linting and automatic code suggestions, follow the instructions here : GitHub - febinjoy/febins-neovim-config. It contains my Neo-Vim configuration. It requires you to create a .config/nvim folder in your home directory. All the configurations I made are using Lua. It is simple, all you will need to do is to clone the repo and let NeoVim install the Lazy and Mason plugins.
Run this to use my config:
git clone https://github.com/febinjoy/febins-neovim-config ~/.config/nvim
Launch nvim to auto-install plugins.
Install Zsh (already done in utilities)
Create history and config files:
touch ~/.zsh_history
nano ~/.zshrc
- Add the following to
~/.zshrc:
ZINIT_HOME="${XDG_DATA_HOME:-${HOME}/.local/share}/zinit/zinit.git"
if [ ! -d $ZINIT_HOME ]; then
mkdir -p "$(dirname $ZINIT_HOME)"
git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
fi
source "$ZINIT_HOME/zinit.zsh"
zinit ice depth=1; zinit light romkatv/powerlevel10k
zinit light zsh-users/zsh-autosuggestions
zinit light zsh-users/zsh-syntax-highlighting
zinit light Aloxaf/fzf-tab
zinit snippet OMZP::git
zinit snippet OMZP::sudo
zinit snippet OMZP::extract
export HISTFILE=~/.zsh_history
export HISTSIZE=10000
export SAVEHIST=10000
bindkey "^[[3~" delete-char
alias ls='ls --color'
alias grep='grep --color'
- Change Default Shell to Zsh:
Installing Zsh and having the config will not automatically switch your shell from bash to Zsh. We need to use the following command to change your shell:
chsh -s $(which zsh)
Then reboot or re-login.
✨ If using Powerlevel10k, you may want a Nerd Font on your terminal.
- My final version:
I have added more options and aliases to my .zshrc according to my preference. Please find it below. Please don't hesitate to use it. You may need to remove some of it if you don’t have the associated tool installed. e.g. fzf:
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
fi
ZINIT_HOME="${XDG_DATA_HOME:-${HOME}/.local/share}/zinit/zinit.git"
if [ ! -d $ZINIT_HOME ]; then
mkdir -p "$(dirname $ZINIT_HOME)"
git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
fi
source "${ZINIT_HOME}/zinit.zsh"
zinit ice depth=1; zinit light romkatv/powerlevel10k

[[ ! -f ~/.p10k.zsh ]] || source ~/.p10k.zsh
TMUX aka Terminal Multiplexer is a powerful utility for terminal management, enabling the user to work with several terminal sessions in one window. It is a game changer in my opinion, which allows the user to easily create, manage, and switch between multiple terminal panes and windows, enhancing productivity and making multitasking easier. TMUX allows session detachment and re-attachment, which is very helpful in keeping persistent sessions on remote servers. It is also highly customisable and is an indispensable utility for any developer, system administrator, or anyone else who works with the command line on a frequent basis.
- Install TMUX:
sudo apt install -y tmux
- Create config file:
nano ~/.tmux.conf
Paste my config or your own.
- Install TPM (Plugin Manager):
git clone https://github.com/tmux-plugins/tpm ~/.tmux/plugins/tpm
- Inside a TMUX session:
Press Ctrl + A then I to install plugins
Press Ctrl + A then r to reload
If you used my TMUX configuration, you will see a themed TMUX window at this point.
In Part 3, we'll focus on securing and hardening the server with firewall rules, SSH configuration, Fail2Ban, and more.
Stay tuned for Part 3: Securing and Hardening the Server!
