What if you were a file?

Let’s say you are this file: /r4ds/do4ds/cohort1/chapter8.Rmd

What if you have a sudden urge to see the world?

The bash command to change directories is cd . In this case, you start at /r4ds/do4ds/cohort1 which is the directory for your (chapter8.Rmd) bedroom.

Any path with .. is a relative path and only works from your current directory.
