Korn Shell: Unix and Linux Programming Manual, Third Edition, The

In-Line Editors

In-line editing provides the ability to edit the current or previous commands before executing them. There are three in-line editing modes available: emacs, gmacs, and vi. The emacs and gmacs modes are basically the same, except for the way Ctl-t is handled. The inline editing mode is specified by setting the EDITOR or VISUAL variables, or with the set –o command. The editing window width is specified by the COLUMNS variable. For lines longer than the window width, a mark is displayed to notify position. The marks >, <, and * specify that the line extends to the right, left, or both sides of the window.

Vi Input Mode Commands
