As developers, we are always looking for a way to increase our productivity to complete our daily tasks faster while keeping some comfort during the execution. Configuring a server can be challenging at the beginning. When you are already comfortable with it, you can feel bored because some things can make you a bit slower:
- If a task takes a long to complete, you have to wait for it to complete or open another terminal.
- Since you don't have a GUI, navigating a folder is hard since even when you know you will be a comeback in a folder because you need to perform some task in another folder, you will retype the command later
- You don't have an autosuggestion that can improve your speed.
- Because of the terminal UI, sometimes, I don't even remember in which folder I'm inside, and I have to type
Ahh! I'm here😆.
- You type slowly 😛! Yes, like me, I wish I could type fast like guys in hacker movies.
In this post, We will see how to improve the user experience when working on the server.
Before we start, here are the requirements to follow this tutorial:
- A VPS running on a Linux distribution in my case, I'm on Ubuntu 18.04. Check out my post on our to perform minimal configuration on a new VPS.
- An SSH client to connect to the server. I use Termius and find it very good.
ZSH stands for Z Shell, which is a shell program for Unix-like operating systems. ZSH is an extended version of Bourne Shell, which incorporates some features of BASH, KSH, TSH. To see all to features provided by ZSH, check out this link.
The installation is pretty simple with the APT package manager:
sudo apt update sudo apt install zsh
Make sure the installation succeeded by checking the version installed:
teco@server:~$ zsh --version zsh 5.4.2 (x86_64-ubuntu-linux-gnu)
Set ZSH as the default shell
The default shell is Bash. We can check by doing this:
teco@server:~$ echo $SHELL /bin/bash
The chsh allow switching from one shell to another. You need to provides the location of the target shell. To get the location of ZSH, do
which zsh and you will get the output
/usr/bin/zsh . Here is the final command to change the shell:
teco@server:~$ chsh -s /usr/bin/zsh
Now log out from the server and log in again.
Since it is the first time we start a session with ZSH, some configurations are needed.
0 to create the .zshrc file with just a comment. Now, open the file
.zshrc created and add the content below:
# Keep 1000 lines of history within the shell and save it to ~/.zsh_history: HISTSIZE=1000 SAVEHIST=1000 HISTFILE=~/.zsh_history
Save the file and exit.
Now the configuration is completed so, let's go to the next step.
Install Oh My ZSH
Oh My Zsh is an open-source, community-driven framework for managing your Zsh configuration. It provides more than 275 plugins and 150 themes to give a good look to your terminal. As we can read on the website:
Oh My Zsh will not make you a 10x developer...but you may feel like one!
Let's clone the Github repository and browse the plugins list:
git clone https://github.com/ohmyzsh/ohmyzsh.git ls ohmyzsh/plugins
Oh My Zsh is installed, now let's update our .zshrc to set a theme and add plugins. Open the .zshrc file and append the code below:
export ZSH=$HOME/ohmyzsh ZSH_THEME="agnoster" plugins=(git z) source $ZSH/oh-my-zsh.sh
- We set a variable ZSH with a value equal to the path of the Oh My Zsh folder. You can give the name you want; just keep it in mind when you need that.
- We set the Zsh theme to "agnoster". The default is "robbyrussell".
- We load two plugins: git and z. git will improve the experience when working with version control, and z make it easy to navigate between folders. We will see it in action later.
- Finally, we will reload the
oh-my-zsh.shfile to update the config. Every time we open a terminal, this configuration will be applied. Nice!
Save the file and exit the file; log out from the server and log in again. Here is what it will look like:
- git plugin in action: I type
- z plugin in action: I inside the folder
~/ohmyzsh/pluginsI want to go back to the home directory; instead of doing
cd ~I type
z ~and I there.
I don't know for you, but I start feeling like I'm a 6x developer 😌
Autosuggestion and syntax highlight
The plugins required are not included in Oh My Zsh plugins. We will add them manually:
git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH/plugins/zsh-autosuggestions git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH/plugins/zsh-syntax-highlighting ls $ZSH/plugins
Make sure are inside the plugins folder as expected:
Now update our plugins list inside the file .zshrc to add these to plugins.
Open the .zshrc file with
Replace the line
plugins=(git z) by
plugins=(git z zsh-autosuggestions zsh-syntax-highlighting)
Save and exit the file; log out from the server and log in again. We can see autosuggestion and syntax highlight in action 🎉
Revert to the previous shell
It may happen you want the switch back to the previous shell, aka Bash. Here are the commands to achieve that:
sudo apt --purge remove zsh rm -rf ~/ohmyzsh rm ~/.zshrc $ chsh -s $(which bash) exit
It is the end of the tutorial where we saw how to enhance our terminal for better productivity using Zsh and Oh My Zsh. You can explore the themes and plugins to add more customization to your terminal.
Here is the link for a cheat sheet about Oh My Zsh. It will give a sneak peek of some plugins, and it will remain to you to go further or not.
Here are other plugins I use:
I hope you find it interesting and see you in the next tutorial 😉.
