Working with directories
Changing directory
The cd (change directory) command is used to, well, change directory. This allows you to change where you are 'standing' at the command line.
Examples
- Change to your home directory: 
cd ~ - Change to your documents directory: 
cd ~/Documents - Change to an absolute path: 
cd /Users/bob/Music 
Making
mkdir will make a directory
Examples
- Make a directory 'test' in the current directory 
mkdir test - Make a directory 'test' at a specific location 
mkdir /Users/alice/documents/test 
Deleting directories
rm -rf (rm: remove) will delete a directory.
Examples
- Delete a directory 'test' in the current directory 
rm -rf test - Delete a specific 'test' directory 
rm -rf /Users/alice/documents/test 
Note: 'rm -rf' is dangerous - it will delete all files and subdirectories without any prompt or ability to undo. Be very sure of the path you have told rm to remove before pressing ENTER
