Error in permissions lesson

[oC-n]

In the lesson on permissions, the command for removing all permissions for other users (non-owner, non-group) is given as chmod a= final.grd. This will instead remove all permissions from owner and group members as well as others. I believe the command should be chmod o= final.grd to remove permissions from other only.

Yep, agree! Want to send a fix @oC-n ? I don't have write access, so @gcapes will need to merge any pr :)

Happy to sort that out, @kynan - just might take me another week or so to get to it, as racing a deadline at present.

@kynan @oC-n,

I included it in my PR #81 . Also, I change the wording from "all" to "others" since it is more appropriate.
