Hello, @mega3707257709! Welcome to the forum.
Did you type ls in the far right panel after the $ prompt, and then click enter?

same thing happened to me, if I type 1s, it doesn’t work, if I copy the 1s written by them and paste it in, it does… No idea why…

It’s ls not 1s => lowercase L and s not the number 1 and s. It’s a command that is short for list.

oh, sorry. Thank you :).

No worries. The distinction between l and 1 is pretty subtle, and without a coding background it’s pretty easy to mistake what the instructions are asking for.

Hello, @stopmyego. Welcome to the forum.
Did you click the Check Work button at the bottom of the console window after executing the ls command? You’ll need to click Check Work after each step in this exercise.

On a few occasions when trying to run the terminal I get an error even though I think I’m inputting exactly what I need to. This happened on the previous exercise as well, I had to restart the exercise and input the exact same thing for it to succeed.
Or I’m crazy, can somebody check this work?

Thanks!
