In this question: what did I do on my linux box, used the rm incorrectly
I basically did a rm instead of a mv.
Anyhow, it turns out the /data folder I deleted which was in my home folder is still present somewhere else in my shell i.e. /home/my_user_id/data
So I guess the one I deleted was just a reference/alias to that folder??
How can I re-create this alias so when I do: cd ~ and then ls I see the /data and /domains folder again. (domains is there as I didn't delete that!)
