My MCQ's are for the lesson "The Unix Shell - Files and Directories" that can be found here

First

If Nelle wanted to count ALL the directories in her current working directory which command should she use … ?

1. ls -a
2. ls
3. ls -F -a
4. pwd

Second

If the output from the Unix command "pwd" shows /users/nelle/molecules … how can you get to Nelle's home directory using an absolute path

1. cd ..
2. cd users/nelle
3. cd .
4. cd /users/nelle

Distortions

1. this will get you to the right place but it is a relative path
2. this looks like an absolute path but if forgets the "/" root directory at the beginning
3. this will not get to the right place and it is a relative path
4. correct answer
