RCHE7 Management II-3 using the VIM editor

Different versions of Vim:

1.vim-minial provides VI and related commands. In the minimum installation of Rhel 7

2.vim-enhanced provides VIM commands. Provides features such as syntax highlighting, file type plug-ins, and spell checking

3.VIM-X11 provides Gvim, which is a vim version that can be run in its own graphics window rather than in the terminal

Three main modes of VIM:

Mode	Function
Command mode	File navigation, cut and paste, and simple commands. Undo, Redo, and other operations are also performed in this mode
Insert mode	General text editing. Substitution mode is a variant of the insert pattern
Ex Mode	Used to save, exit, and open files, as well as search, replace, and other more complex operations. This mode can insert the output of the program into the current file, as well as configure vim and so on

To switch to insert mode, the system provides the available commands that correspond to different keys

Key	Results
I	Switch to insert mode and start inserting (inserting) before the current cursor position
A	Switch to insert mode and start inserting (attach) after the current cursor position
I	Moves the cursor to the beginning of the current line and switches to insert mode
A	Moves the cursor to the end of the current line and switches to insert mode
R	Start with the character under the cursor and switch to replace mode. When in replace mode, no text is inserted, and each word entered nonspacing replaces the characters in the current document
O	Opens a new row below the current line and switches to insert mode
O	Opens a new row above the current line and switches to insert mode

Move

Key	Results
W	Move the cursor to the beginning of the next word (W will skip the punctuation)
B	Move the cursor to the beginning of the previous word (b will skip the punctuation)
（	Move the cursor to the beginning of the current or previous sentence
）	Move the cursor to the beginning of the current or next sentence
