echo command in the terminal

Hey there! hope you are ok.

I still don't see the point of the echo argument to be useful? obviously if it is there it is for a reason, but I cannot visualise why we need this for?

Hi Silvia! echo is used to print output to the screen - similar to console.log() in javascript. So, say you made a terminal script, you could calculate 2+2 and see the result of the calculation in the terminal with the echo command:

 #!/bin/bash
let a=2+2
echo $a

Let me know if this helps!
