| + | ====== The Vi Editor ====== | ||
| + | |||
| + | The vi editor is a display-oriented text editor. It is used for creating text files. It is not used to create font formatting. It is not a mode-less editor (as common on modern PCs). Everything that you type does not necessarily appear on the screen. Vi has two modes, editing and command mode. Editing is used for data entry, while command is used to navigate and manipulate the data entered during the editing mode. | ||
