I've also had a few questions on this. The font could certainly make the distinction clearer. For programming, this is a useful font-selection criteria, along with slashed zeros to distinguish 0 and O. The font is probably something for the styles repository though? |
The graphics are pretty old, doubtful it's been standardized. Welcome a PR that fixes the fonts |

I can confirm that this can be confusing - it has been an issue in our courses as well. However: as far as I understand, you are not supposed to show the direct rendered output of Carpentry classes anyway: you are supposed to show your own terminal where you type those commands and ideally talk while doing it. With this in mind, I suggest instead to maybe add a sentence in the right places to the instructions, reminding instructors to mention specifically that this is a letter or number depending on the place. In addition: do we have a case when a terminal by default chooses a font that makes this difficult? |
These lessons can (and are) used in a variety of ways. Some instructors don't show the notes: some always do.

In the class, several learners confuse the
-l
with the-1
, especially in the serif'd fonts in the graphic.I'm not sure if we can clarify the graphic, or at least give a few tips in the lesson or instructor guide that
-l
is NOT-1
