Update: 1-Aug-2019: The example mentioned in this post is now redundant. Use iTerm'sstatus bar instead.

iTerm2 is a very powerful replacement to the built-in terminal. You can read more about whyhere.

This post will focus on one specific functionality I recently explored and found useful:Badges and is meant for beginners unfamiliar with iTerm2

Hello World

Let's start with a "Hello World" example.

• Go to "iTerm2 > Preferences > Profiles"
• Add the text "HelloWorld" to the input "General -> Basics -> Badge"

• If you open up a new iTerm2 window, you should now see this:

• This badge will be displayed in each tab. Split the window into two tabs and this is what you'll see.
  

• Now lets make the badge display something useful like the name of the user and the machine. To do this, we'll first need to installShell Integration
  

• Now, go back to the Preferences panel and change the Badge to\(session.username)@\(session.hostname)
  

• iTerm will now display a more useful badge
  

Important: The "Install Shell Integration" step will have to be done oneach host you ssh into before you'll see the correct label.

Enjoy,
Vivek.

P.S: Badges also support more advanced features like user-defined variables. Experiment with them to get the look-and-feel you need. All you need to know is some basic bash scripting
