USE1.6 CLI File editors

Running programs using the CLI often also includes editing files without a GUI available. Many programs are available and are also often suggested in tutorials and by other people. It is of importance to being able to navigate file editing using different editors and understanding how to write files and exit the editor.

Most common editors will all be included here, meaning one should be taught and the other need to be mentioned for completeness:

• VI/Vim
• Emacs
• Nano

• USE1.1 Command Line Interface
• USE1.3 UNIX File System Tree

• Define the abilities of a CLI based file editor
• Discuss what a CLI file editor needs to be able to do and how it should behave
• Demonstrate the usage of an editor to open a file in write mode and save the file
• Show how to quit an editor (relevant for all editors)
• Solve undo and redo operations to recover from changes and restore them
• Indicate how to use the mouse pointer
• Define how to copy and paste using the clipboard
• Contrast differences between available editors
  • Summarize the controversy between Emacs and Vim users
