This article is about how linux uses vi to operate. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Vi (vim) is a very common editor on Linux, and many Linux distributions have vi (vim) installed by default. There are a lot of vi (vim) commands, but if you use them flexibly, you will be much more efficient. Vi is the abbreviation of "visual interface" and vim is vi IMproved (enhanced version of vi). Vi is sufficient for general system management and maintenance, and vim can be used if you want to use code highlighting. The following vps detective collates the use of vi tutorials: contains a basic introduction to vi, mode of use, file opening and closing save, insert text or new lines, move the cursor, delete, restore characters or lines, search, and so on, is a more suitable for beginners to learn vi tutorial.

Vi has three modes: insert mode, command mode, and low-line mode.

● insert mode: you can enter characters in this mode, press ESC to return to command mode.

● command mode: you can move the cursor, delete characters, etc.

● low-line mode: you can save files, exit vi, set vi, find, and other functions (low-line mode can also be seen as in command mode).

Open, save, and close files (used in vi command mode)

Insert text or line (used in vi command mode, enter insert mode after executing the following command, press ESC key to exit insert mode)

A / / add text to the right of the current cursor position

I / / add text to the left of the current cursor position

A / / add text at the end of the current line

I / / add text at the beginning of the current line (the beginning of a line that is not empty)

O / / create a new line above the current line

O / / create a new line below the current line

R / / replace (overwrite) the current cursor position and some subsequent text

J / / merge the line of the cursor and the next behavior line (still in command mode)

Move the cursor (used in vi command mode)

1. Use the up and down arrow keys

2. In command mode: h to left, j to down, k up, l to right.

The spacebar moves to the right, Backspace to the left, Enter to the beginning of the next line,-to the beginning of the previous line.

Delete or restore characters or lines (used in vi command mode)

X / Delete the current character

Nx / / Delete n characters starting from the cursor

Dd / / Delete the current line

Ndd / / Delete n lines down, including the current line

U / / undo the previous operation

U / / undo all actions on the current line

? vpser / / search the cursor for the vpser string

N / / search down for the previous search action

N / / search up the previous search action

Skip to the specified line (used in vi command mode)

N + / / Jump n lines down

N-/ / Jump n lines up

NG / / Jump to the line with line number n

G / / Jump to the bottom of the file

7. Set the line number (used in vi command mode)

: set nu / / displays the line number

: set nonu / / cancel displaying line number

Copy and paste (used in vi command mode)

Yy / / copies the current line to the cache, or you can use "ayy copy," an is the buffer, or a can be replaced with any letter from a to z to complete multiple copy tasks.

Nyy / / copies the current line down n lines to the buffer, or you can use "anyy copy," an is the buffer, or a can be replaced with any letter from a to z to complete multiple copy tasks.

Yw / / copies characters from the beginning of the cursor to the end of the word.

Nyw / / copy the n words starting with the cursor.

Conclusion: although the vi (vim) tutorial has more commands, as long as you practice frequently, I believe you will quickly master it, and at the same time, it will bring more efficiency to your work or study. If you don't know what mode you are in, you can press ESC twice to return to command mode. There will be one final reminder: pay attention to case!

100d delete line 100th

: 1100 mo $moves the contents of one hundred lines to the last line.

7. About inserting

I: enter insert mode before the character in the current position

I: insert at the beginning of the current line

A: enter insert mode after the character in the current position

A: insert at the end of the current line

8. About revocation

U: undo the last change
