Learning version control and git can be learned through many GUI apps that make it easy for first-timers to learn the basics, but at a certian point you might want to devel into the command line way of doing things.

There are some advantages and certian disadvantages at I've found over time when using command line, but overall its been a positive experience for me. I actually find its easier to navigate directories and find files and open apps with command line

Here is a short list of basic commands

To LIST out a directory's files and folders use

User$ LS

Here is the result

index.html
page1.html
page2.html
styles.css
images

Note that "images" has no file extension, therefore is a folder

To CHANGE DIRECTORY and go into a folder use

User$ CD *name-of-folder*

To CHANGE DIRECTORY and go OUT a folder use

User$ CD ..

To MAKE a DIRECTORY use

User$ MKDIR *name-of-directory-to-delete*

To REMOVE a DIRECTORY use

User$ RMDIR *name-of-new-directory*

This only works for an empty folder, to delete a non-empty folder use

User$ RM -R *name-of-directory-to-delete*

To create a new file use

User$ TOUCH name-of-new-file.txt

Make sure to include the files extension and this will create a new file in the dicrectory you are currently in, you can check with LS to list out the directory to see if the file has been created

To REMOVE a file use

User$ RM name-of-file-to-delete.txt
