Bash Path
A path tells Bash where a file or folder is. Folder names are joined with a slash /.
A path that starts with / is an absolute path. Any other path is a relative path, read from the folder you are in.
Use a path to a file
ls /usr/bin/bash
/usr/bin/bash
Go down two folders at once
cd my_directory/docs
pwd
/home/user/my_directory/docs
