vi Editor Commands
The vi editor is a powerful command editor used to modify Unix commands.
Note:
It is possible to damage a file, which might render the system
inoperative, by improper use of a file or command editor on system files.
This section is only meant as a review for those familiar with vi
commands.
Using vi
To edit a file using the vi editor on a file with a name <file_name>, from the
command line, type:
vi <file_name>
Use the following commands to edit and then close the file.
vi Modes
vi is a three-mode line editor: it has a command mode, a line mode, and an
editing mode. It is very useful for editing a file, for navigating within an open file,
and for opening or saving a file.
Command mode For moving around within an open file
Editing mode For text editing in the file
Line mode For file opening, saving, closing, exiting
To enter vi in the line mode, from the command mode, type : (colon).
