Thanks hbar1st. There’s only one hint and says that the variable needs to be created in the bottom line of the .sh file. So, I understand one needs to echo that variable into the file…
Thanks ILM - The file only contains the shebang “!#/bin/bash” at that point. The file can`t be edited directly in the environment, so I can’t just write the variable in the .sh file directly
That is not true. They never said to use echo. The hint is telling you to write the line of code in the file. So open the file in the editor and do that.
The file can be edited if you have not changed the permissions by mistake. Click the Reset button if you think you made a mistake and it will reset the environment for you so you can edit the file. All files are editable in this environment provided you have not modified their permissions.
