Pimping up My Linux Terminal

2021-03-31T00:00:00+06:00

The purpose of this post is to be my quick, copy-paste source of the commands that I use to set up my terminal on a new *nix system. However, if someone else finds it useful, that’d be some cherries on top.

This command prompt in the below image is the end goal.

Assuming, I’m on a standard pc/server with Ubuntu Linux and I have CLI access with sudo. For other Linux distros or MacOS, some commands might be slightly different.

Step-1: Confirm that Zsh is up-to-date¶

While on most of the Linux systems Zsh is present by default, on others that’s not the case. So, let’s make sure about it.

$ sudo apt install zsh

Confirm the version. Oh-my-zsh recommends Zsh to be 5.0.8 or higher.

$ zsh --version
zsh 5.8 (x86_64-ubuntu-linux-gnu)

Also, you gotta make sure that git (recommended v2.4.11 or higher) is also installed on the system.

Step-2: Install Oh-my-zsh, the fun “configuration” framework¶

Install directly from the source.

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

In the last step of this installation, it will ask to set Zsh as THE shell. Go ahead.

Now we have the default prompt from Oh-my-zsh.

Now, let’s pimp up the prompt. Shall we?

Step-3: Install `powerlevel10k`, a powerful prompt theme¶

I love the powerful Zsh theme powerlevel10k. More on why this theme is awesome.

Let’s install it on top of oh-my-zsh.

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

Now, gotta set ZSH_THEME="powerlevel10k/powerlevel10k" in ~/.zshrc by adding that manually in the file.

Step-4: Make sure the prompt looks like as you want¶

In this step, I’m gonna bring in my already open-sourced Zsh config file aka .zshrc.

# deleting the current one & get my personal one from GitHub
$ rm .zshrc
$
$ wget https://raw.githubusercontent.com/kmonsoor/dot-files/master/.zshrc

I kept the powerlevel10k configs as comments so that Zsh doesn’t complain if I use the config file early. Have to set ZSH_THEME="powerlevel10k/powerlevel10k" in the ~/.zshrc as well.

Otherwise, once the powerlevel10k theme will run for the first time by Zsh, a very friendly step-by-step prompt will run you through towards a desirable prompt for you. Also, whenever you want, you can invoke the config-wizard by executing p10k configure on the shell.

Now is the time to enable the changes by restarting Zsh and enjoy the new config and the powerful prompt.

$ exec zsh

Optional¶

Also, I usually install this very useful, but external plugin zsh-syntax-highlighting for oh-my-zsh.

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

Don’t forget to activate the plugin by including it in ~/.zshrc. For that, add zsh-syntax-highlighting inside the list of other plugins.

plugins=( plugin_a plugin_b zsh-syntax-highlighting)
