Directories

We have our parent directory which is Home and inside the directory we have 2 folders those are children of the Home directory. Inside the Document Folder which has 2 has a folder and a file. The 2 are both children of Document folder.

Understanding Structure

In some cases because Home is the parent directory that means we can put / to specify that is the parent directory. To get to the Download Folder we need to go to /Downloads/ and if we want to go to Sub Folder we have go to /Documents/Sub Folder.

Note: In some cases parent directory can be specify like this ./

If I'm in Document Folder and I want to be in Home I have to go back so ../ That just means parent folder

Commands

In most operating system they use cd and ls.

For Windows you need to use dir. You can also use tree but that only applies to windows.

[...] means optional parameter and (...) is required parameter

ls [dir] or dir [dir]
