Using the shell

Today, most computer users use a GUI or a Graphical User Interface to interact with their computers. Before GUIs existed, users would use a terminal to interact with computers. In contrast to a GUI, a terminal is text-based. A shell runs on the terminal, which will accept user commands.

Navigating around

One of the most common commands is ls. It lists files and directories.

ls # Lists the current files and directories in current directory

Of course, it is not very useful to list files and directories without knowing what the current directory is. The command pwd can tell you where you currently are.

pwd

To change the current directory, one uses the cd command:

cd ~ # ~ expands to the home directory of the current user

Removing and creating things

To remove a file or folder, you can run:

rm -rf <folder or filename> # Replace the brackets and text with the actual folder and filename
