You know https://github.com/dylanaraps/neofetch?
It has a lot of overhead within and it's slow, IMHO.
So I made my own small one. It shows path, time, success indication for the last command (time in red/green), git branch, coloured dirs, emoticons for every shell to indicate where a drop table * is OK, and wisdom. It's just a WIP'n'boilerplate for more.
How?

infoOS=`sw_vers -productName`
infoOS+=`printf " "`

Talk is cheap. Show me the code. (Linus Torvalds)
Every program has two purposes: The one for which it was written and another for which it wasn't. (Alan J. Perlis)
Every great developer you know got there by solving problems they were unqualified to solve until they actually did it. (Patrick McKenzie)
One of my most productive days was throwing away 1000 lines of code. (Ken Thompson)
In theory, there is no difference between theory and practice. But, in practice, there is. (Jan L. A. van de Snepscheut)
If something is expensive to develop, and somebody's not going to get paid, it won't get developed. So you decide: Do you want software to be written, or not? (Bill Gates)
Any fool can write code that a computer can understand. Good programmers write code that humans can understand. (Martin Fowler)
Before software can be reusable it first has to be usable. (Ralph Johnson)
Inside every large program, there is a small program trying to get out. (C. A. R. Hoare)
Functional programming is a radical and elegant attack on the whole enterprise of writing programs. It's very different from the 'do this and then do that' programming mentality. You have to rewire your brain in quite a different way. (Simon Peyton-Jones)
Sometimes, the elegant implementation is just a function. Not a method. Not a class. Not a framework. Just a function. (John Carmack)
A program is like a poem: you cannot write a poem without writing it. (E. W. Dijkstra)

The best error message is the one that never shows up. (Thomas Fuchs)
Computers are good at following instructions, but not at reading your mind. (Donald Knuth)
Simplicity is about subtracting the obvious and adding the meaningful. (John Maeda)
Never trust a computer you can’t throw out a window. (Steve Wozniak)

That’s what’s cool about working with computers. They don’t argue, they remember everything and they don’t drink all your beer. (Paul Leary)
Telling a programmer there's already a library to do X is like telling a songwriter there's already a song about love. (Pete Cordell)
Fancy algorithms are slow when n is small, and n is usually small. (Rob Pike)
Programming languages, like pizza, come in only two sizes: too big and too small. (Richard Pattis)
Simplicity carried to the extreme becomes elegance. (Jon Franklin)
Without requirements or design , programming is the art of adding bugs to an empty text file. (Louis Srygley)
What I cannot build, I do not understand. (Richard Feynman)
Deleted code is debugged code. (Jeff Sickel)
The object-oriented version of spaghetti code is, of course, 'lasagna code'. Too many layers. (Roberto Waltman)
So much complexity in software comes from trying to make one thing do two things. (Ryan Singer)
There's nothing more permanent than a temporary hack. (Kyle Simpson)
An evolving system increases its complexity unless work is done to reduce it. (Meir Lehman)
No one in the brief history of computing has ever written a piece of perfect software. It's unlikely that you'll be the first. (Andy Hunt)
Good design adds value faster than it adds cost. (Thomas C. Gale)
One of the best programming skills you can have is knowing when to walk away for awhile. (Oscar Godson)
Every good idea will be discovered twice: once by a logician and once by a computer scientist. (Philip Wadler)

A program is never less than 90% complete, and never more than 95% complete. (Terry Baker)
People have an enormous tendency to resist change. They love to say, 'We've always done it this way.' I try to fight that. (Grace Hopper)
Commenting your code is like cleaning your bathroom - you never want to do it, but it really does create a more pleasant experience for you and your guests. (Ryan Campbell)
Sometimes the idea behind a program is one small creative effort. Just like in a short story, one little twist in the plot is the whole idea behind it. (Dan Bricklin)
