I seem to be following the instructions and am not getting an error message but my little green box doesn’t get ticked…? please help


There are three checkmarks in that exercise. Which one are you referring to?

The last one is to run a command which causes something to happen, did it?

Since most of it is about editing a file, what is the content of that file if you read it again from the file system?


When working on the exercise, I follow the directions and type:

alias pd=“pwd” CtrlO
file1 CtrlX

but it wont check off the green box. What am I doing wrong? Nothing in the nano exercise seems to work.
