Pimp my terminal

pimp my term!

As a Linux user, I enjoy working with the terminal, and I find it an especially powerful tool. Therefore, I've spent quite a long time customizing it, and here is my definitive guide for terminal customizations.

First I thought I would only create a short post with some of the tweaks I like. But I had so many things I wanted to show that this started to become a considerably long post. So I've decided to publish it now, with as many tips as I can write, and I'll be updating it with new tips & tricks.

If you want to download my configuration files, check my `~/.dotfiles` repository. Notice that there I save my own configuration files, and some of them might not work out of the box for you, but following this guide, you'll be able to customize everything on your taste.

If you find anything from this post that could be improved, or know about other settings that may be cool enough to also include them, don't hesitate to contact me via email (daniel@drasite.com) or opening an issue on my GitHub dotfiles repository.

1. Patched Fonts

I want to start talking about patched fonts as many of the customizations that I'll be explaining later may depend on them. Patched fonts consist of regular fonts to which some additional symbols have been added. That way, you can show special icons (such as your OS icon), or add new shapes to your prompt.

The most successful project is nerd-fonts, which includes many of the most used fonts, and also a DIY patcher, in case you want a different one. My favorite font from this project is HACK bold

Nerd Fonts

Nerd Fonts is a project that patches developer targeted fonts with a high number of glyphs (icons). Specifically to add a high number of extra glyphs from popular 'iconic fonts' such as Font Awesome, Devicons, Octicons, and others.

2. Colorizing the terminal

2.1. Color Scheme

On the way to the definitive terminal, there is nothing that improves its looks more than customizing its color-scheme, so this will be our start point. Searching on the Internet, you'll be able to find plenty of themes, but the easiest way to apply them is using Gogh. This tool doesn't require any installation and allows you to pick your favorite colors from a long list of different prebuilt schemes.

This is the list of compatible terminals:
Gnome Terminal, Pantheon Terminal, Tilix and XFCE4 Terminal. It also works on iTerm for macOS

bash -c "$(curl -sLo- https://git.io/vQgMr)"
gogh script preview

Flat Remix

The color-scheme that I'll be utilizing in all the screenshots is based on the color palette used for Flat Remix icon theme, which I personally love 😍.

If you also like it, you can manually copy it from the following box, or run the command below for an automatized installation (notice that the script is based on Gohg and, therefore, will only work if you are using a compatible terminal).


Install Flat Remix color-scheme:
bash -c "$(curl -sLo- https://git.io/JvvDs)"

2.2. Some aliases

Some of the commands you already have installed, in fact, do support color highlighting, for example: ls, grep, and diff. In case you want these commands always to have the color option enabled, you can write aliases in your terminal configuration file (.bashrc / .zshrc) to force them.

alias ls='ls --color=auto'
alias grep='grep --color=auto'
alias fgrep='fgrep --color=auto'
alias egrep='egrep --color=auto'
alias diff='diff --color=auto'

You can replace as well some common commands with newer, more colorful utilities. Just keep in mind, when using aliases for this purpose, that you may be overriding a useful tool with another one that you may not have installed. This can be especially important if you are using the same dotfiles for multiple machines, where you may not have the same packages. To avoid this, you can program the alias so that it'll be only configured in case the needed command is available. Here's the template:

# This is a template; Replace "new-command" and "alias-name"
command -v new-command > /dev/null && alias alias-name='new-command ...'

2.3. Man pages

Man pages support coloring too, which makes them so much visually pleasing. For it, man uses a bunch of variables where you can configure the color escape sequences you want to use.

export LESS_TERMCAP_mb=$'\e[1;32m'
export LESS_TERMCAP_md=$'\e[1;32m'
export LESS_TERMCAP_me=$'\e[0m'
export LESS_TERMCAP_se=$'\e[0m'
export LESS_TERMCAP_so=$'\e[01;33m'
export LESS_TERMCAP_ue=$'\e[0m'
export LESS_TERMCAP_us=$'\e[1;4;31m'
colorized man pages

2.4. LS & TREE from the future

lsd command preview


The next gen ls command.
This project is heavily inspired by the super colorls project but with some little differences. For example it is written in rust and not in ruby which makes it much faster.

Alias ls=lsd
command -v lsd > /dev/null && alias ls='lsd --group-dirs first'
Alias tree=lsd
command -v lsd > /dev/null && alias ls='lsd --tree'

2.5. TOP from the future


htop is an interactive system-monitor process-viewer and process-manager. It is designed as an alternative to the Unix program top. It shows a frequently updated list of the processes running on a computer, normally ordered by the amount of CPU usage. Unlike top, htop provides a full list of processes running, instead of the top resource-consuming processes. htop uses color and gives visual information about processor, swap and memory status. htop can also display the processes as a tree.

Alias top=htop
command -v htop > /dev/null && alias top='htop'


Another TUI based system monitor, this time in Rust!

Alias top=ytop
command -v ytop > /dev/null && alias top='ytop --per-cpu'
YTop over light background
command -v ytop > /dev/null && alias top='ytop --per-cpu -c default-dark'


Resource monitor that shows usage and stats for processor, memory, disks, network and processes.

Bashtop includes flat-remix and flat-remix-light themes

Alias top=bashtop
command -v bashtop > /dev/null && alias top='bashtop'

2.6. CAT & LESS from the future


A cat clone with syntax highlighting and Git integration.

Configure BAT to use the color-scheme from the terminal
alias bat='bat --theme=ansi-dark'
BAT over light background
alias bat='bat --theme=ansi-light'
Alias cat=bat
command -v bat > /dev/null && alias cat='bat --pager=never'
Alias less=bat
command -v bat > /dev/null && alias cat='bat'

2.7. LOLcat

lolcat LOLcat... 🤣️ Get rainbows and unicorns everywhere! This tool commonly appears used together with neofetch, adding a stunning rainbow effect to its output. neofetch with lolcat

3. Bash customizations

Bash (Bourne-again shell) is the most popular shell program and comes preinstalled on many Unix-based operating systems. It may not be the most customizable shell available, but it does support prompt customizations using color codes and escape sequences.

In case you are using this shell and want to save some of the settings provided in this post, you can write them to your local .bashrc file so that they are executed before the interactive shell is launched.

3.1.Custom prompt

Bash uses a variable named PS1 to store the prompt code. This value is readen every time it needs to be written again, in order to maintain its output updated. Therefore, you can override the default prompt by setting a new string to PS1.

For bash, I usually like to have a clean prompt with some coloring, only showing the current relative directory. Here is my personal configuration:

PS1=" \[\033[1;36m\]\w >\[\033[1;34m\]>\[\033[0m\] "
custom bash prompt

But, if you prefer, you can create some more complex prompts as well:

PS1="\n \[\033[0;34m\]┌─────(\[\033[1;35m\]\u\[\033[0;34m\])─────(\[\033[1;32m\]\w\[\033[0;34m\]) \n └> \[\033[1;36m\]\$ \[\033[0m\]"
powerline like bash prompt

Powerline like bash prompt

In case you installed a patched font as described before, now you'll be able to use any kind of symbols for building your prompt. These fonts include many powerline symbols that allow you to fully customize your terminal without having to install any external plugin.

You can search for custom glyphs here: https://www.nerdfonts.com/cheat-sheet

OS_ICON=   # Replace this with your OS icon
PS1="\n \[\033[0;34m\]╭─────\[\033[0;31m\]\[\033[0;37m\]\[\033[41m\] $OS_ICON \u \[\033[0m\]\[\033[0;31m\]\[\033[0;34m\]─────\[\033[0;32m\]\[\033[0;30m\]\[\033[42m\] \w \[\033[0m\]\[\033[0;32m\] \n \[\033[0;34m\]╰ \[\033[1;36m\]\$ \[\033[0m\]"
powerline like bash prompt with patched font

You can even make it look like you are using Zsh with Powerlevel10k installed, just by tweaking the PS1 variable!

OS_ICON=  # Replace this with your OS icon
PS1="\n \[\033[0;34m\]╭─\[\033[0;31m\]\[\033[0;37m\]\[\033[41m\] $OS_ICON \u \[\033[0m\]\[\033[0;31m\]\[\033[44m\]\[\033[0;34m\]\[\033[44m\]\[\033[0;30m\]\[\033[44m\] \w \[\033[0m\]\[\033[0;34m\] \n \[\033[0;34m\]╰ \[\033[1;36m\]\$ \[\033[0m\]"
powerline like bash prompt with patched font

In case you want to create your own personalized prompt below you'll find all the color codes and some of the most used escape sequences to build it.

Color codes

    "\[\033[0m\]"       # no colors (reset)
    "\[\033[0;30m\]"    # black
    "\[\033[0;31m\]"    # red
    "\[\033[0;32m\]"    # green
    "\[\033[0;33m\]"    # yellow
    "\[\033[0;34m\]"    # blue
    "\[\033[0;35m\]"    # magenta
    "\[\033[0;36m\]"    # cyan
    "\[\033[37m\]"       # white

    # emphasized (bolded) colors
    "\[\033[1;30m\]"    # black
    "\[\033[1;31m\]"    # red
    "\[\033[1;32m\]"    # green
    "\[\033[1;33m\]"    # yellow
    "\[\033[1;34m\]"    # blue
    "\[\033[1;35m\]"    # magenta
    "\[\033[1;36m\]"    # cyan
    "\[\033[1;37m\]"    # white

    # background colors
    "\[\033[40m\]"    # black   
    "\[\033[41m\]"    # red     
    "\[\033[42m\]"    # green   
    "\[\033[43m\]"    # yellow  
    "\[\033[44m\]"    # blue    
    "\[\033[45m\]"    # magenta 
    "\[\033[46m\]"    # cyan    
    "\[\033[47m\]"    # white   

Common prompt escape sequences

View the complete list
    \d     the date  in  "Weekday  Month  Date"  format
           (e.g., "Tue May 26")
    \h     the hostname
    \j     the  number of jobs currently managed by the shell
    \n     a newline
    \t     the current time
    \u     the username
    \w     the current working directory
    \W     the basename of the current working direc­tory
    \$     if the effective UID is 0, a #, otherwise  a $

3.2.Completion Plugin

Bash completion is a functionality through which bash helps users type their commands faster and easier. It accomplishes that by presenting possible options when users press the tab key while typing a command.

Once you have it installed, you can enable it by adding the following lines to your ~/.bashrc file:

if [ -f /usr/share/bash-completion/bash_completion ]; then
    source /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
    source /etc/bash_completion

3.3.Enable Globstar **

shopt -s globstar

Globstar option enables the ** pattern, which works pretty similar to the single * but in a recursive way, so it can look in all directories and subdirectories for matches.

When the globstar shell option is enabled, and * is used in a pathname expansion context, two adjacent *s ** used as a single pattern will match all files and zero or more directories and subdirectories. If followed by a /, two adjacent *s will match only directories and subdirectories.

4. Zsh customizations

Zsh is a much more configurable shell with tons of plugins and themes that will make your terminal look awesome and even improve your workflow. For this shell customization possibilities are almost limitless, so now I'll simply explain the settings and themes I use.

One key difference of Zsh is that it doesn't come with preconfigured settings as other shells like bash or fish, so I would suggest copying some of my settings as a starting point, particularly if you are installing it for the first time.

If you are using this shell and want to save some of the settings provided in this post, you can write them to your local .zshrc file so that they are executed before the interactive shell is launched.

4.1. Configure Keybindings

One of the first things I quickly noticed using Zsh is that many of the keys and shortcuts that I was used to, coming from bash, wouldn't work at all or resulted in unexpected behaviors. Even END and HOME keys didn't work. So here you have all the keybinding configuration I use:

    bindkey '^[[2~' overwrite-mode
    bindkey '^[[3~' delete-char
    bindkey '^[[H' beginning-of-line
    bindkey '^[[1~' beginning-of-line
    bindkey '^[[F' end-of-line
    bindkey '^[[4~' end-of-line
    bindkey '^[[1;5C' forward-word
    bindkey '^[[1;5D' backward-word
    bindkey '^[[3;5~' kill-word
    bindkey '^[[5~' beginning-of-buffer-or-history
    bindkey '^[[6~' end-of-buffer-or-history

4.2. Misc settings

This is only a list of my personal settings, just in case they help you:

    unsetopt NO_BEEP
    unsetopt NO_MATCH
    setopt AUTO_CD
    setopt BEEP
    setopt NOMATCH
    setopt NOTIFY
    setopt SHARE_HISTORY
    setopt HIST_FIND_NO_DUPS
    setopt HIST_SAVE_NO_DUPS
    setopt HIST_VERIFY
    setopt HIST_BEEP
    setopt NULL_GLOB

    autoload compinit && compinit

4.3. Powerlevel10K

zsh powerlevel10k prompt gif demo

There are a number of Powerline ZSH themes available, now. The developers of this theme focus on four primary goals:
  1. Give users a great out-of-the-box configuration with no additional configuration required.
  2. Make customization easy for users who do want to tweak their prompt.
  3. Provide useful segments that you can enable to make your prompt even more effective and helpful. We have prompt segments for everything from unit test coverage to your AWS instance.
  4. Optimize the code for execution speed as much as possible. A snappy terminal is a happy terminal.

POWERLEVEL10K is a fast reimplementation of POWERLEVEL9K with even some extra features. It even maintains the same variable names, so you won't need to change your configuration if you are coming from POWERLEVEL9k.

One thing that I love from POWERLEVEL10K is that, if you have yet no configuration, when you launch it the first time, it will show you a guide asking your preferences. During this process, it shows multiple examples, making it so much easier to customize.

You can always launch the configuration wizard by running p10k configure

zsh powerlevel10k prompt
s=' ' # fix too wide icons
POWERLEVEL9K_PROMPT_ON_NEWLINE=true # <- Set this to false for simgle line prompt
POWERLEVEL9K_OS_ICON_CONTENT_EXPANSION='${P9K_CONTENT} $(whoami | grep -v "^root\$")'
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(os_icon root_indicator ssh dir dir_writable vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(vi_mode status command_execution_time background_jobs time ram)


# ---- load POWERLEVEL10K ---
source /usr/share/zsh-theme-powerlevel10k/powerlevel10k.zsh-theme

4.4. Useful plugins

For Zsh many people usually installs some kind of configuration framework such as "Oh My Zsh", which can be really useful (I guess...), but I prefer to do it manually. It isn't something complicated, you just need to install the plugin you want and then source it in your local ~/.zshrc config file. Speaking about the installation, you can do it manually, just downloading the plugin and copying it to the directory you want, or using a package manager, which commonly installs the plugin inside /usr/share/zsh/plugins/.


Fish-like fast/unobtrusive autosuggestions for Zsh.
It suggests commands as you type based on history and completions.
zsh autosuggestions plugin
source /usr/share/zsh/plugins/zsh-autosuggestions/zsh-autosuggestions.zsh

Syntax highlighting

This package provides syntax highlighting for the shell Zsh. It enables highlighting of commands whilst they are typed at a Zsh prompt into an interactive terminal. This helps in reviewing commands before running them, particularly in catching syntax errors.
zsh syntax highlighting plugin
source /usr/share/zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

5. Other customizations

To finalize this post, I'll be dropping here some scripts and settings that help me optimize my workflow.

Useful functions

Find shortcut

find <str>

Similar to locate, this function allows you to search files recursively, but it only shows matches placed within the current directory. The script overrides the original find command adding this useful shortcut, which can be used by writing find followed by the string you want to use. Vanilla find command needs more than one parameter to be able to return useful results, so this modification won't alter its functionality, therefore, you will still be able to use it normally as well.

find() {
    if [ $# = 1 ]
        command find . -iname "*$@*"
        command find "$@"


lazygit "<Message>"

In case you use git, this function will save you some extra commands. Running it will preview and add to git's cache all the changes from the current directory. Following this, they will be committed using the provided message and pushed to the current branch.

lazygit() {
    git status .
    git add .
    git commit -m "$@"
    git push origin HEAD
Advanced lazygit
Similar to the previous function, this git shortcut executes git add, commit, and push and additionally supports commit amends. It handles the rebase process for you so that you don't have to clean the branch after applying a fixup.
lazygit() {
lazygit [OPTION]... 

    GIT but lazy

        --fixup <commit>        runs 'git commit --fixup <commit> [...]'
        --amend                 runs 'git commit --amend --no-edit [...]'
        -f, --force             runs 'git push --force-with-lease [...]'
        -h, --help              show this help text
    while [ $# -gt 0 ]

        case $key in
                shift # past argument
                shift # past value
                shift # past argument
                shift # past argument
                echo "$USAGE"
                return 0
                shift # past argument
    git status .
    git add .
    if [ $AMEND -eq 1 ]
        git commit --amend --no-edit
    elif [ "$COMMIT" != '' ]
        git commit --fixup "$COMMIT"
        GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash "$COMMIT^"
        git commit -m "$MESSAGE"
    git push origin HEAD $([ "$FORCE" -eq 1 ] && echo '--force-with-lease')

Git graphical log

Pimp my terminal

pimp my term!

As a Linux user, I enjoy working with the terminal, and I find it an especially powerful tool. Therefore, I've spent quite a long time customizing it, and here is my definitive guide for terminal customizations.

First I thought I would only create a short post with some of the tweaks I like. But I had so many things I wanted to show that this started to become a considerably long post. So I've decided to publish it now, with as many tips as I can write, and I'll be updating it with new tips & tricks.

Kali 2020.1 visual updates

Today Kali 2020.1 has been released and with it lots of new visual changes for its desktop. The following is a brief feature summary for this release:

  • Non-Root by default
  • Kali single installer image
  • Kali NetHunter Rootless
  • Improvements to theme & kali-undercover
  • New tools

But here I'm not going to explain all the latest improvements that have been introduced in this version but to reveal all the different themes and visual modifications that come with it. By the way, an essential change that I do want to emphasize is the switch to a default non-root user, with the username "kali" and password "kali". For more of the reasons behind this switch, please see this blog post: kali.org/news/: Kali Default Non-Root User.

Kali 2019.4 new themes 🐉

Today Kali Linux 2019.4 just launched, and I'm so excited to announce that, for the last two months, I've been working together with the Kali team developing all its new look. The first noticeable change is the move from Gnome to Xfce as the default desktop. This change was made to make default Kali more comfortable for low resource computers, as it is also commonly used on small ARM devices that don't have as high performance as an average desktop.

If you don't want to leave Gnome, don't worry. Kali now offers a Gnome build for you with some of the new desktop themes. As this release was focused on the Xfce DE change, most of the latest changes were intended for this desktop. For next releases, more changes will be available for all kali flavors to get them "close" to a similar user experience no matter the environment you run.

Build a PHP minimal Blog

When I was about to create this new fancy blog for my website, I was wondering what would be the easiest way to implement it without losing much time programming. Moments later, I was doing the same thing I always do when something could be just straight forward. Using an existing framework? Would you say...
... 🤦‍♂️

Noup! I created my own ultra-minimal framework to handle it. But that is great because now I can blog in my blog about the blog! 🤯
If that makes any sense at all.
