From an almost fully automated pipeline to a fully automated pipeline
Some call it shell, others call it the terminal, command line. Whatever it is called, it is the lifeblood of programmers using a unix-based system.
My first encounter with the Z shell was during my internship in 2018 summer. My tech lead was troubleshooting some docker issues on my laptop and he remarked:
"Bash sucks. Use z shell, it is so much better"
Every programmer's goal is to maximise productivity while minimising the amount of effort expended.
Without diving into the history of bash and Z shell, let's talk about some wins I have experienced in my workflow:
cd tab autocomplete
For bash, the tab autocomplete shows a list of directories matching the current word, while Z shell allows me to cycle through the directory list with a double tab.
It is not a big deal when there is only one directory that matches the current word, but can save a tiny bit of time when there are multiple matches and the names are long.

We can't talk about Z shell without mentioning the awesome oh-my-zsh framework, which comes with themes and plugins that supercharges the Z shell itself.
It is similar to jetpack from wordpress, which does a lot of magic for us.
In the words of oh-my-zsh's maintainers:
Oh My Zsh will not make you a 10x developer...but you might feel like one
z command: smart cd based on history
Gone are the days when we have to manually cd or Open in Terminal in our working directory.
Just do a z <my_working_directory> and Z shell will (hopefully) get you to the destination in a jiffy. Not to mention that the command has a tolerance for typo error.
Note: The path that we want to z into should be manually navigated to at least once, so that Z shell will "remember" it for future use.

git branch no more
Let's take a moment to reflect on how much time was wasted by typing git branch in our entire lifetime.
With the agnoster theme, the current branch is clearly shown in the terminal.

Autocomplete suggestion
Z shell is all about being lazy to save precious time, and this takes the cake because no one got the time to type in the same command more than once.
Autocomplete suggestions shows up as a muted gray color as we type the commands, and we just have to hit → to accept the suggestion.

I'm sure these are just barely scratching the surface of Z shell and bash, but for what it's worth, these features have certainly turned me into a lazier and more productive programmer!
