How many molecules in the air the bats are flying through?

One, ah ah ah… Two, ah ah ahhh … Hold on, this might take a while

In my first weeks with it i had a subdirectory named “home” somewhere in a project directory I was done with. It must have been finger memory but when i went to delete it I typed

rm -Rf /home

That slash ruined my day

Well explained. Thanks for spelling it out.
