Sometimes only words will do. Graphical user interfaces (GUIs) were a great advance, creating an easy route into computers for non-technical users. But for complex tasks, GUIs can block off choices and require a circuitous route even for simple tasks.

Enter the command line: the blinking cursor many thought had faded away in the 1990s. For getting instructions from user to computer -- in a clear, quick, and unambiguous form -- nothing beats the command line. It never disappeared on UNIX and Linux systems, and thanks to Raspberry Pi OS, a new generation is discovering how it simplifies complex tasks and lets you carry out simple ones instantly.

Build essential skills, including:

• Read and write text files
• Find and install software
• Manage removable storage
• Use Secure Shell (SSH) for remote access
• Write disk images to SD cards
• Browse the web from the command line
