Vim copy, Paste, delete, undo, replace, cursor move, etc. usage

When I was in touch with Linux, I used the nano text editor, and personally felt that his greatest advantage was convenience and speed. Open files, modify files, to exit are very fast and simple. This is better than Vi,vim, but the nano can not display color words, the whole row can not be deleted, editing various configuration files, the total feeling is not very convenient. For the nano of these shortcomings, vim can be a good solution, and vim open the file, the word is color, this point root editplus,eclipse is the same, for the program, it is more cool. The following operations are in the command state, do not enter the insertion state, if entered into the Insert State, [ESC] exit the input state

One, the cursor moves

We do not think that the cursor movement is not important, in fact, it is the foundation, better cursor movement, copy, paste, delete, etc. to be more handy, into the editor inside, the mouse can not be used.

Cursor movement

h or LEFT ARROW key (←)

20h or 20 (←)

The cursor moves one character to the left

The cursor moves 20 characters to the left,

J or DOWN ARROW key (↓)

20J or 20 (↓)

Move the cursor down one line

Move the cursor down 20 lines,

K or Up ARROW key (↑)

20k or 20 (↑)

Move the cursor up one line

The cursor moves up 20 lines,

L or right ARROW key (→)

20l or 20 (→)

The cursor moves one character to the right

The cursor moves 20 characters to the right,

One thing to note here is that you don't use the keypad to enter numbers, or you'll enter the pattern directly. Personally feel that mastering the above, basically can meet our requirements of the cursor movement, see

Vim

We can judge by the number in the lower right corner of the editor, which line we want to jump to, if we want to be more precise, set NU sets the environment variable, let it show the line number is the best

Ctrl + F screen "down" to move one page, equivalent to [PAGE DOWN] key (common)

Ctrl + b screen "up" to move one page, equivalent to [PAGE UP] key (common)

Ctrl + d screen "down" to move half a page

Ctrl + u screen "Up" move half page

Ctrl + E screen "down" to move one line

Ctrl + y screen "up" to move one line

+ cursor moves to the next column of non-whitespace

- cursor moves to the previous column of non-whitespace

N<space> that n means "number", pressing the number and then pressing the SPACEBAR, the cursor moves the n characters of the line to the right. For example 20<space>, the cursor moves 20 character distances to the back.

N<enter> N is a number. Move the cursor down n rows (common)

0 or function key [Home] This is the number "0": Move to the front of the line prompt (common)

$ or Function key [end] moves to the last face of this line prompt (commonly used), where the $ in the regular is the meaning of the end, so that understanding can remember

H cursor moves to the first character of the line at the top of the screen, h you write it as the initials of the header, so it's okay to remember

The m cursor moves to the first character of the line in the central of this screen, m you write it down as middle abbreviation

L Move the cursor to the first character of the line at the bottom of the screen, l you write it down as the last abbreviation.

G move to the last line of this file (common)

NG N is a number. Move to the nth row of this file. For example, 20G will move to line 20th of this file.

GG moved to the first line of this file, equivalent to 1G Ah! Common

Second, delete, copy, paste, undo

Delete, copy, paste, undo

X, x in a line of words, X is the backward deletion of a character (equivalent to the [Del] key), X is to delete a character forward (equivalent to [backspace] is the backspace bar) (commonly used)

Nx

N is a number that continuously deletes n characters backwards. For example, I want to continuously delete the 10 characters after the cursor, "10x".

Dd

Yy

Copy all data from the same character as the cursor to the beginning of the line

P, p p copies the copied data, pastes it on the next line of the cursor, and p pastes the copied data to the previous line of the cursor

J combine data from one row of the cursor to the same line

C repeatedly delete multiple data, you can use the up and down keys to decide to delete the cursor above, or the following

U undo. Common

Ctrl + R undo revocation. Common

Three, block selection, find, replace

Block selection, find, replace

V character selection, the cursor will pass through the place of the white selection!

V -line selection, the line of the cursor will be reversed white selection!

Ctrl + V block selection, you can select the data in a rectangular way

Y Copy the anti-white place.

D Remove the anti-white place

V or V

CTRL + V

As can be seen from the above, V and V are mainly carried out, row selection, and Ctrl + V is the choice of the column, in terms of flexibility, CTRL + V more flexible.

/string

? string

Look under the cursor for a name called string string

Look above the cursor for a name called string string

N

N

Forward lookup, the search for a string, can be understood as next

Reverse lookup, search out the string, can be understood as not next

Find

To illustrate, the difference between N and N, made an example, look at the left, the left is the result of searching ddd, the yellow black word is the result of the search, at this time, we can press N or N, in these 4 search chunks within, to switch.

The order of N is 12341234

The order of N is 43214321

In a word, n is from top to bottom, n is from bottom to top

: n1,n2s/string1/string2/g Here N1 is the number of start rows to find, N2 is the number of rows to find the end. ": 2,7s/ddd/fff/g" in line 2nd, line 7th, replace DDD with FFF

: 1, $s/string1/string2/g look for the string1 string from the first line to the last line, and replace the string with string2! Common

: 1, $s/string1/string2/gc look for the string1 string from the first line to the last line, and replace the string with string2! and display the prompt character before the substitution to the user to confirm (confirm) whether need to replace! Common

Four, save, exit, environment variables

Save, exit, environment variables

: W

: w!

Write the edited data to the hard drive archive (common)

Left after storage

Forced to leave after storage

ZZ This is the uppercase Z Oh! If the file does not change, then do not store away, if the file has been changed, then save and leave!

: w [filename] Save As

: R [FileName] in the edited data, read into the data of another file. The file "filename" is also added to the following line of the cursor

:! Command temporarily leaves VI to command column mode to perform command display results! For example ":! Cat./test "To view the contents of the test file in the current folder in VI

I,i,a,a,o,o,r,r into the insertion mode, although there are differences, the feeling is not very different, put together

ESC exits insert mode and enters command mode

: Set nu Displays the line number, which, when set, displays the row number of the row in the prefix of each row, which is useful when we are modifying the configuration file, it is much easier to know how many rows.

: Set Nonu with Set nu, cancel line number

Five, summary

Personally feel that the above operation can meet, 80%--90% of the needs of people, if the operation of multiple files, I think a variety of development tools, more convenient than vim.
