How I Made My Terminal Beautiful (And Actually Enjoy Staring at It All Day)

I spend most of my day SSH’d into servers. For years that meant staring at a white-on-black PuTTY window, squinting at walls of text, and constantly running git status because my prompt told me absolutely nothing. One day I decided to fix that for good.

This guide walks through the full setup, both the server side and the SSH client side, to get a terminal that is genuinely pleasant to look at and actually useful. Everything here is open source.

Here is what the end result gives you:

A prompt that changes color and shows branch name, dirty state, and ahead/behind counts the moment you enter a git repo
Commands light up in cyan as you type them, and turn red if they don’t exist
Dim ghost suggestions from your command history appear as you type, and you accept them with the right arrow key
File listings with icons, colors, and git status per file
Syntax-highlighted file previews instead of plain cat output
A fuzzy finder for files and command history
A color scheme that is easy on the eyes for long sessions

Let’s get into it.

What We Are Installing

There are two sides to this setup.

On the server (the remote Linux machine you SSH into):

Zsh as the shell, replacing Bash
Oh My Zsh as the plugin framework
Powerlevel10k as the prompt theme (this is where the git magic happens)
zsh-autosuggestions for history-based ghost text
zsh-syntax-highlighting for live command coloring
zsh-completions for better tab completion
eza as a modern replacement for ls
bat as a modern replacement for cat
fd as a modern replacement for find
ripgrep as a modern replacement for grep
fzf as a fuzzy finder for everything

On your local machine (where you sit and type):

A terminal that supports true color (24-bit) and Unicode
The JetBrains Mono Nerd Font (for the icons in the prompt)

Step 1: Ditch PuTTY

I know, I know. PuTTY has been the go-to SSH client forever. But it was designed in a 256-color world, and that limitation makes everything look washed out no matter what you do on the server side. Switching your SSH client is the single biggest visual upgrade you can make.

Option A: Windows Terminal (Recommended)

Windows Terminal is open source (MIT license), built into Windows 11, and available for Windows 10 from the Microsoft Store or from the GitHub releases page. It has tabs, GPU-rendered text, full true color support, and excellent font rendering.

It uses the OpenSSH client that already ships with Windows 10 and 11, so connecting to a server is just:

ssh user@your-server.com

No extra setup needed for basic SSH.

Option B: Alacritty

If privacy is your top priority, Alacritty is the one. Written in Rust, Apache 2.0 license, zero telemetry, GPU-accelerated. It is minimal by design and does one thing well.

Install it from the releases page or via winget:

winget install Alacritty.Alacritty

Step 2: Install the Nerd Font

This is the step people forget and then wonder why they see little boxes instead of icons. The font has to be installed on your local machine, the one you are sitting in front of. Not the server.

Download JetBrains Mono from nerdfonts.com, extract the zip, select all the .ttf files, right-click, and choose “Install for all users”.

Then set it as your terminal font:

Windows Terminal: Open Settings (Ctrl+,), go to your profile, and set the font to JetBrainsMono Nerd Font, size 11 or 12.

Alacritty: Create the config file at %APPDATA%\alacritty\alacritty.toml:

[font]
size = 11.0

[font.normal]
family = "JetBrainsMono Nerd Font"
style = "Regular"

[font.bold]
family = "JetBrainsMono Nerd Font"
style = "Bold"

[window]
padding = { x = 12, y = 12 }
opacity = 0.95

Step 3: Apply the Color Scheme

The whole setup uses a Tokyo Night inspired palette. Dark blue-gray background, soft foreground colors, and distinct but not harsh accent colors. Easy on the eyes for long sessions.

For Windows Terminal

Open Settings, click “Open JSON file” at the bottom left, and paste this into the "schemes" array:

{
    "name": "Terminal Glow",
    "background": "#1A1B26",
    "foreground": "#C0CAF5",
    "cursorColor": "#BB9AF7",
    "selectionBackground": "#2A2E3F",
    "black": "#15161E",
    "red": "#F7768E",
    "green": "#9ECE6A",
    "yellow": "#E0AF68",
    "blue": "#7AA2F7",
    "purple": "#BB9AF7",
    "cyan": "#7DCFFF",
    "white": "#A9B1D6",
    "brightBlack": "#414868",
    "brightRed": "#F7768E",
    "brightGreen": "#9ECE6A",
    "brightYellow": "#E0AF68",
    "brightBlue": "#7AA2F7",
    "brightPurple": "#BB9AF7",
    "brightCyan": "#7DCFFF",
    "brightWhite": "#C0CAF5"
}

Then in your SSH profile, set "colorScheme": "Terminal Glow". Here is a full profile example you can drop into the "profiles" list:

{
    "name": "My Server",
    "commandline": "ssh user@your-server.com",
    "colorScheme": "Terminal Glow",
    "font": {
        "face": "JetBrainsMono Nerd Font",
        "size": 11
    },
    "opacity": 95,
    "useAcrylic": true,
    "padding": "12"
}

For Alacritty

Add these colors to your alacritty.toml:

[colors.primary]
background = "#1a1b26"
foreground = "#c0caf5"

[colors.cursor]
cursor = "#bb9af7"
text = "#1a1b26"

[colors.selection]
background = "#2a2e3f"
text = "#c0caf5"

[colors.normal]
black   = "#15161e"
red     = "#f7768e"
green   = "#9ece6a"
yellow  = "#e0af68"
blue    = "#7aa2f7"
magenta = "#bb9af7"
cyan    = "#7dcfff"
white   = "#a9b1d6"

[colors.bright]
black   = "#414868"
red     = "#f7768e"
green   = "#9ece6a"
yellow  = "#e0af68"
blue    = "#7aa2f7"
magenta = "#bb9af7"
cyan    = "#7dcfff"
white   = "#c0caf5"

Step 4: Set Up SSH Keys and Config

While we are on the client side, let’s set up key-based auth and an SSH config so you never type long connection strings again.

If you don’t have a key yet:

ssh-keygen -t ed25519 -C "your@email.com"

Copy it to your server:

type $env:USERPROFILE\.ssh\id_ed25519.pub | ssh user@your-server.com "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Then create C:\Users\YourUsername\.ssh\config:

Host *
    ServerAliveInterval 60
    ServerAliveCountMax 3
    AddKeysToAgent yes

Host myserver
    HostName your-server.com
    User root
    IdentityFile C:\Users\YourUsername\.ssh\id_ed25519

Now connecting is just ssh myserver. The Host * block applies keepalive settings to all connections so your sessions don’t drop when you step away.

If you manage many servers, the Host * block handles the shared defaults and each server only needs two lines:

Host web1
    HostName web1.example.com

Host db1
    HostName db1.example.com
    User postgres

Enable the SSH agent so you only type your key passphrase once per session:

Get-Service ssh-agent | Set-Service -StartupType Automatic
Start-Service ssh-agent
ssh-add $env:USERPROFILE\.ssh\id_ed25519

Step 5: Server-Side Setup

Now SSH into your server and install the good stuff. This section assumes Ubuntu or Debian.

Install Zsh and the CLI tools

sudo apt update
sudo apt install -y zsh git curl wget unzip fontconfig bat fd-find ripgrep fzf

On Debian/Ubuntu, bat is installed as batcat and fd is installed as fdfind. Create symlinks so you can use the short names:

sudo ln -sf $(command -v batcat) /usr/local/bin/bat
sudo ln -sf $(command -v fdfind) /usr/local/bin/fd

For eza (the modern ls replacement), check if it is in your repos first:

sudo apt install eza

If that doesn’t work (older Ubuntu/Debian), grab it from GitHub:

EZA_VERSION=$(curl -s https://api.github.com/repos/eza-community/eza/releases/latest | grep '"tag_name"' | head -1 | sed -E 's/.*"v([^"]+)".*/\1/')
ARCH=$(dpkg --print-architecture)
curl -sL "https://github.com/eza-community/eza/releases/download/v${EZA_VERSION}/eza_${ARCH}-unknown-linux-gnu.tar.gz" | sudo tar xz -C /usr/local/bin/

Install Oh My Zsh

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

It will ask if you want to change your default shell to Zsh. Say yes.

Install Powerlevel10k and the plugins

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git \
  ~/.oh-my-zsh/custom/themes/powerlevel10k

git clone --depth=1 https://github.com/zsh-users/zsh-autosuggestions \
  ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions

git clone --depth=1 https://github.com/zsh-users/zsh-syntax-highlighting \
  ~/.oh-my-zsh/custom/plugins/zsh-syntax-highlighting

git clone --depth=1 https://github.com/zsh-users/zsh-completions \
  ~/.oh-my-zsh/custom/plugins/zsh-completions

Configure .zshrc

Back up your current config first:

cp ~/.zshrc ~/.zshrc.bak

Then replace it. Open ~/.zshrc in your editor and paste the full config below. It is long, but every section is commented so you know what each part does.

# Powerlevel10k instant prompt (keep at the very 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

# ── Load Powerlevel10k config ──
[[ -f ~/.p10k.zsh ]] && source ~/.p10k.zsh

Configure the Prompt

The easiest way is to run the built-in wizard:

p10k configure

It walks you through a series of visual choices and builds the config for you. Pick the options you like and it writes ~/.p10k.zsh automatically.

If you prefer a pre-made config that gives you a clean, minimal, two-line prompt with full git info, you can grab the one from the install script instead. The key things it sets up:

Left side: OS icon, current directory, git status
Right side: last command exit code, execution time, user@host (only in SSH), time
Branch name in green when clean, amber when dirty, red on conflicts
Ahead/behind arrows for push/pull status
Staged, unstaged, and untracked file counts
Previous prompts collapse to a simple arrow to save screen space

Step 6: Log Out and Back In

Close your SSH session and reconnect. Your new shell should greet you with a clean, colorful prompt. If you see little boxes instead of icons, go back to Step 2 and make sure the Nerd Font is installed on your local machine and set in your terminal app.

Daily Workflow

Here is what changes in your day-to-day work.

Navigating files: Just type ls and you get colored output with icons for each file type, directories grouped at the top. Type ll for a detailed view with git status per file and relative timestamps like “2 hours ago” instead of raw dates. Type lt for a tree view.

Reading files: cat now shows syntax-highlighted output. If you want line numbers, use catn. For the full pager experience with header and line numbers, use catf.

Finding things: Press Ctrl+R for fuzzy search through your command history. Press Ctrl+T for fuzzy file search. Both use a nice floating popup with the same color scheme.

Git repos: The moment you cd into a git repo, the prompt shows the branch name. Make some changes and you immediately see counts for staged, unstaged, and untracked files. The color shifts from green to amber. If you are behind the remote, you see a down arrow with the commit count.

Typo catching: As you type a command, it appears in cyan if it is valid. If you mistype something, it turns red before you even press Enter.

History suggestions: Start typing a command you’ve used before and a dim suggestion appears. Press the right arrow to accept it. This alone saves a huge amount of typing over a day.

Sudo shortcut: Forgot to type sudo? Press Escape twice and it gets prepended automatically.

Quick Reference

Command	What it does
`ll`	Detailed file list with git status and relative timestamps
`lt`	Tree view, two levels deep
`gs`	Short git status
`gl`	Pretty git log, last 20 commits with graph
`catf some-file`	View file with syntax highlighting and line numbers
`Ctrl+R`	Fuzzy search command history
`Ctrl+T`	Fuzzy search files
`reload`	Reload .zshrc after editing it
`p10k configure`	Re-run the prompt wizard
`ESC ESC`	Prepend sudo to current command

Troubleshooting

Icons are broken (boxes or question marks): The Nerd Font is not installed on your local machine, or your terminal is not using it. Check your terminal’s font settings.

Colors look washed out: Your terminal does not support true color. This is the PuTTY problem. Switch to Windows Terminal or Alacritty.

Prompt is slow in very large git repos: Powerlevel10k is fast, but repos with millions of files can still lag. Add this to your ~/.p10k.zsh:

typeset -g POWERLEVEL9K_VCS_MAX_INDEX_SIZE_DIRTY=10000

Want to go back to bash: Your old .bashrc is untouched. Just run:

chsh -s /bin/bash

That is the whole setup. It takes about 10 minutes to go through and the difference is night and day. Your terminal goes from a wall of white text on black to something that actually communicates useful information through color and structure, without you having to think about it.

The Lazy Way

If you don’t want to go through all the steps manually, here is the complete install script that does everything in one go. Upload it to your server, make it executable with chmod +x terminal-glow.sh, and run it with sudo bash terminal-glow.sh.

A word of caution though. Never blindly paste scripts from the internet into your terminal. Not this one, not any other. Take a few minutes to read through it first and understand what it does. A single script running with sudo has full control over your system. Trust, but verify.

You can grab the full installer script below and upload it to your server.
