Vi is a visual editor. The meaning of the visual editor is that you can see them when editing text. Vim in Linux is an enhanced version of vi. It has features such as color and highlight, which is very helpful for programming.

Basic usage:

Start vim: At a Linux prompt, type vim (or use vim myfile to edit an existing file) to start it.

Vim Exit: Press Esc to return to command line mode, and then type ":". The cursor stays in the bottom line, type "q" again (if forced exit, add "! "), And then press Enter.

VIM commands on mobile

Move the cursor effectively in the current row

* Fx: move the cursor to the next x of the current row. Obviously, x can be any letter, and you can use; to repeat your previous f command.

* Tx: similar to the preceding command, but it is moved to the left of x. (This is really useful)

* Fx: similar to fx, it is used to search back.

* W: move the cursor forward to a word.

* B: Move a word behind the cursor.

* 0: move the cursor to the beginning of the current row.

* ^: Move the cursor to the first letter of the current row.

* $: Move the cursor to the end of the row.

*): Move the cursor to the next sentence.

* (: Move the cursor to the previous sentence.

Move the cursor effectively throughout the file

* : Move a screen down.

* : Move the screen up.

* G: to the end of the file

* NumG: move the cursor to the specified row (num ). (For example, 10 Gb is to 10th rows)

* Gg: to the beginning of the file

* H: move the cursor to the screen

* M: move the cursor to the center of the screen

* L: move the cursor to the screen

**: Read the string at the cursor and move the cursor to where it appears again.

* #: It is similar to the above, but it is looking in the opposite direction.

*/Text: search for the string text from the current cursor and reach the place where the text appears. You must press enter to start the search command. If you want to repeat the previous search, press n.

*? Text: similar to the above, but in the opposite direction.

* Ma: Mark a bookmark with the name a at the current cursor position. Only lowercase letters are allowed. You can't see the existence of bookmarks, but it is already there.

* 'A: Go to bookmarks. Note that this is not a single quotation mark. It is generally located on the left of 1 of most keyboards.

* '.: The last time you edited the file. This command is useful, and you do not need to mark it yourself.

Valid text for moving large segments

* V: select by character. Frequently used mode, so try it yourself.

* V: select by row. This is especially useful when you want to copy or move many lines of text.

* : Select by block. Very powerful. This function is available only in a few editors. You can select a rectangle and the text in the rectangle is highlighted.

When selecting a mode, use the arrow keys and commands described above (motion ). For example, vwww highlights the three words in front of the cursor. Vjj will highlight the current line and the following two lines.

Once you highlight the selection area, you may want to perform some operations:

* D: paste the selected content to the clipboard.

* Y: copy the selected content to the clipboard.

* C: paste the selected content to the clipboard and enter the insert mode.

If you know exactly what you want to copy or cut, you do not need to enter the visual selection mode. This will save time:

* D {motion}: Cut the characters crossed by the motion command to the clipboard. For example, dw cut a word and dfS cut the character from the current cursor to the next S to the clipboard.

* Y {motion}: similar to the above, but it is a copy.

* C {motion}: similar to d {motion}, but enters the insert mode at last.

* Dd: Cut the current row.

* Yy: copy the current row.

* Cc: Cut the current row and enter the insert mode.

* D: cut from the cursor position to the end of the row to the clipboard.

* Y: copy the current row.

* C: similar to D, and finally enters the insert mode.

* X: Cut the current character to the clipboard.

* S: similar to x, but enters the insert mode at last.

Y + y copies the current position of the cursor in the whole row

Y + w: copy the cursor to the entire word.

If n + y + w is pressed by 3yw, the cursor is located at the end of the word and the last two words (three words in total) are copied together.

If n + y is pressed by 3yy, the line at the cursor position is copied together with the following two lines.

Pasting is simple. Press p.

Use multiple clipboard

Many editors only provide one clipboard. There are many VIM instances. The clipboard is called a register in VIM ). You can list all register names and their contents defined currently. The command is ": reg ". It is best to use lower-case letters as the register name, because some of the upper-case letters are occupied by VIM. The register command is double quotation marks.

For example, we want to copy the current row to register k. You should press "kyy. (You can also use V "ky. Why ?) Now the current row should already exist in register k until you copy something into Register k. Now you can use the "kp" command to paste the content in register k to the desired position.

Commonly used delete text commands in vim:

D + the left arrow key continuously presses d and the left arrow key to delete the character before the cursor position

D + The up arrow key deletes the row where the cursor is located and the previous row at the same time.

D + the arrow key to delete both the cursor position and the next row

N + d + the arrow key is used to delete the rows that contain the cursor and n rows that are up.

The n + d + downstream direction keys are the same as the n + d commands.

D. Delete all words behind the row where the cursor is located

X deletes the last character from the cursor location.

X deletes the character before the cursor position
