Command :! Ls :!! Run the previous shell command: r! The command reads the input of the command and inserts it, for example, r! Ls will first execute ls and then read the content: w!

Grep all: cd directory change the current working directory to the directory indicated by directory: sh starts a sub-shell and returns vi using ^ d (ctrl + d: so file read and execute the macros and abbreviations in command vi in shell program file (avoid using control keys and symbols, do not use the K, V, g, q, v, *, =, and function keys.) function: map key command_seq defines a key to run command_seq, such as map e ea, at any time, you can move e to the end of a word to append text: map displays all the defined Macros in the status line: umap key to delete the key macro: AB string1 string2 defines an abbreviation to replace string1 with string2 when string1 is inserted. When you want to insert text, type string1 and Press Esc. Then the system inserts string2: AB to display all abbreviations: una string cancels the abbreviation of string. In vi, the indent text option is used to insert the moving width when ctrl + I or tab is inserted. The moving width is defined in advance: set ai Enable Automatic indent: set sw = n set the moving width to n characters n> make n rows move one width to the right, for example, 3> move each row of the next three rows to the right to move the width. If n is omitted, the current row is shifted to the right. To facilitate Text Selection, VIM introduces the Visual mode. To select a text segment, first move the cursor to the beginning of the segment, press v in normal mode to enter the visible mode, and then move the cursor to the selected content at the end of the segment (move to the beginning of the line ^, end of the line $ ). Note that the character of the cursor is included in the selection area. In this case, you can perform some operations on the selected text. Common (visual mode) Commands include: x or d cut (that is, delete the selected text and enter the clipboard) y replace all characters of the r character with the new u ~ All letters are written in lower case, written in upper case, and reversed case. After the command is input, VIM returns to the normal mode and can be pasted by p or P. Command for copying and pasting in Normal Mode: v enters the visual mode p or P to paste the clipboard content at the current position, p sticks to the character behind the cursor, P sticks to the front and has to admit, although the visual mode is introduced, copying and pasting in VIM is still troublesome, which may be the only drawback of VIM. In addition, VIM introduces the Select mode, which is similar to the visual mode. Combine key definitions and option settings.
