Explain what these two commands do by experimenting with them and seeing what happens:

$cd ~

$cd - 

The grandparent directory: Can you find TWO ways to move into the grandparent directory in a single command? That is, how can you move from
/Users/erin/Documents/Photos/Selfies/
to
/Users/erin/Documents/
by executing cd just once? Find TWO ways to do this. One way should use an absolute path and the other should use a relative path.

If I have several directories within my Photos directory, like so: /Users/erin/Documents/Photos/Instagram/
/Users/erin/Documents/Photos/NikonPics/
/Users/erin/Documents/Photos/PanoShots/
/Users/erin/Documents/Photos/Selfies/

How move from within the Selfies folder to the Instagram folder using one cd command that uses a relative path?

Up to this point, we have used ls without any arguments. However, ls can take an argument. What happens when you give ls the following types of arguments?:

1. a directory
2. a file

Say you have accidentally named a directory with spaces in the name Files for Qualifying Exam You try to list the contents of this directory by executing the following command?

$ls Files for Qualifying Exam

However, this doesn't work as expected.

A. Why doesn't this work? What is the computer trying to do?
B. What is a proper command required to list the contents of this directory?

This is just for fun and is not due…

What do you think the difference is between these…
/Users/erinnishimura/Documents/
and
/Users/erinnishimura/Documents
?
