Editor to share with you how to use the text editor vim under linux, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Edit command for text file: vim

1. Three state modes of vim

1) Command mode (default)

Note: enter ": Q!" in command mode. You can exit vim.

2) editable mode (enter editable mode by typing lowercase "I" in command mode; press Esc to exit to command mode)

Note: lowercase I, insert at the current cursor; lowercase a, insert after the current cursor.

3) Last line mode (enter through command mode, press Esc to exit to command mode)

Function: execute non-text editing commands on the last line of the file, save, open the file, write the file name, etc.

For example, the purpose of ": W" is to fill in the file name

For example, the purpose of ": wq" is to save and exit after filling in the file.

For example, "/", look up from top to bottom

For example, "?" , look from the bottom up

2. Basic operation of vim

1) Open the file

The vim file name opens and enters command mode.

2) Editing the file

In command mode, enter lowercase I to enter edit mode

3) Save the file and exit

When editing is finished, press Esc to return to command mode and enter ": W" (add a file name if there is no file name)

Then type: Q to exit.

3. Edit operation of vim (in command mode)

1) copy operation

Lowercase "yy" copy single line

2 lines at the "2yy" copy cursor

……

"nyy" copies the cursor out of n lines.

2) paste operation

Lower case "p" is pasted to the next line of the current cursor

Uppercase "P" is pasted to the next line of the current cursor

3) Delete operation

"dd" deletes the current line

"2dd" deletes the current two lines at the cursor

……

4) open for line increment

Lowercase "o" and insert a blank line on the next line at the current cursor

Capitalize "o" and insert a blank line on the previous line at the current cursor

4. Find and replace operation of vim (in the last line mode)

1) find operation

Purpose: to find lines that contain keywords

Enter "/ find object" in command mode to find it from top to bottom and press n to find (next)

Enter "? find object" in command mode to find it from top to bottom, press n to find (next)

Enter: wq (Save and exit).

5. Advanced operation of vim 1) setting of line number

Enter ": set nu" in the last line mode to display the line number of the file

Enter ": set nonu" in the last line mode to turn off the line number of the display file

Vi / .vimrc

2) Editing settings of ~ / .vimrc

3) concurrent operation of multiple files

This operation is convenient for multiple files to copy and paste each other.

Command: vim file name 1 file name 2 file name 3...

Command: ": args" displays the names of multiple files currently open at the bottom, [name of the current file]

Command: ": next" toggles display of the next document

Command: ": prev" toggles display of previous document

Command: ": first" toggles display of the first document

Command: ": last" toggles the display of the last document.

4) undo and restore of operation

Note: whether it is u undo or ctrl+r restore, if the file cannot be saved.

Lowercase u:change before (undo the most recent action by line, step by step, in timeline units) to already at oldest change (undoable multiple steps)

Uppercase U: undo only one step

Ctrl+r:change after (resumes the undone action step by step on a timeline by line) until already at oldest change

Ctrl+R: restore the revoked, one step at a time

How to copy a row, paste and delete a row of data in vi text editing under linux

When using vi, you sometimes want to copy a row of data directly, then paste a row or delete a row of data directly.

The method of copying a row of data

Place the cursor in front of the line you want to copy and press the yy key twice

Then place the cursor where you want to copy it and press the p key on the keyboard

To delete a line, move the cursor over the line you want to delete and press the dd key twice

Here are the key instructions:

XQuery X: in a line, x deletes one character backward (equivalent to del key) and X deletes one character forward (equivalent to backspace key).

Dd: delete the entire line where the cursor is located.

Ndd: n is a number. Starting with the cursor, delete the downward n columns.

Yy: copy the line where the cursor is located.

Nyy: n is a number. Copy the downward n line where the cursor is located.

P: P pastes the copied data to the next line of the cursor, and P pastes it to the previous line of the cursor.

U: undo the previous operation

CTRL + r: redo the previous operation.

Decimal point'.': repeat the previous action.
