(Big Data Engineer Learning Path) Step two VIM editor----vim document editing

One, vim repeat command 1. Repeat the last command

In normal mode . (decimal point) means the last command operation is repeated

Copy test files to a local directory

$ cp /etc/protocols .

Open a file for editing

$ vim protocols

Normal mode input x , delete the first character, the input . (decimal point) will be deleted again a character, in addition to also can be repeated dd delete operation

2. Execute commands of the same number of times

Enter Normal mode input N<command> , n indicates the number of repetitions, and the following is the practice:

Open file file for editing

$ vim protocols

Below you can do the following exercises in turn:

• Input 10x , delete 10 consecutive characters
• Input 3dd , 3 lines of text will be deleted

In normal mode, you can also dw daw delete a word with or (delete a word), so you can easily associate (n with the dnw corresponding number ) to delete n words

Ii. Quick jump of cursors

In normal mode, the following command allows the cursor to be quickly reversed to the specified position, we discuss the rapid implementation of the inline jump and in-line jump

1. Jump between rows

Command	Description
nG(n shift+g)	Cursor moves to nth row (if no line number is displayed by default, enter command mode first :set nu to display line numbers)
gg	Cursor moves to the first row
G(SHIFT+G)	To the last line

Let's practice it:

Open the practice document with VIM

$ vim protocols

Do the following exercises in turn:

• Quickly jump to line 9th and delete the row
• Go back to the first line, delete 8 rows down
• Jump to the end of the document and delete the row

tip: After you have completed the jump, you can use the Ctrl+o quick to go back to the previous (before the jump) cursor position , this technique is very practical, such as when you write code, suddenly think of a bug, need to change, this time you jump over to change, just need to press Ctrl+o You can go back to where you were before. Vim will be waiting for you to explore with a lot of similar tips.

2. In-line jump

In normal mode, use the following command to jump within a line in a word

Command	Description
w	To the beginning of the next word
e	To the end of the next word
b	To the beginning of the first word
ge	To the end of the previous word
0Or^	to the wardrobe.
$	To end of line
f<字母>	Search backwards < letters > and jump to the first matching position (very useful)
F<字母>	Search forward < letters > and jump to the first matching position
t<字母>	Search backwards < letters > and jump to a letter before the first matching position (not used)
T<字母>	Search forward < letter > and jump to a letter after the first matching position (not used)

Do the following exercises in turn:

• In normal mode, jump to a line, use w jump to the beginning of a word, and then use dw the word delete
• In normal mode, use e jump to the end of a word and use ~ the letter that contains the cursor to capitalize or lower case

Third, copy paste and cut 1. Copy and paste text

• Use replication in normal mode y

  • In normal mode, yy the entire line where the cursor is copied ( 3yy representing the replication of 3 rows)
  • In normal mode, y^ copy to the beginning of the line, or y0 . Does not contain the character at which the cursor is located.
  • In normal mode, y$ copy to end of line. The character where the light is contained.
  • In normal mode, yw copy a word.
  • In normal mode, y2w copy two words.
  • In normal mode, yG copy to the end of the text.
  • In normal mode, y1G copy to the beginning of the text.

• Use paste in normal mode p

  • In normal mode, p (lowercase) represents pasting to the cursor (bottom)
  • In normal mode, P (uppercase) means pasting to the front of the cursor (top)

Open the file into normal mode practice the above command, you can now feel free yy to

$ vim protocols

2. Cut and paste

In fact, the dd deletion of the command is cut, each time you dd delete the contents of the document can be used p to paste, also this allows us to achieve a very refreshing function-exchange up and down line:

ddp, so simple, that it implements the fast Exchange cursor where the line is with the line below it

Iv. Summary

In this section you should have mastered several frequently used operations, including fast inter-line movement and fast inline movement, as well as cutting and copying and pasting operations, and I hope you will be able to practice more skillfully, and once you have mastered these operations, you can greatly improve your productivity.

V. Practice of thinking

The commands and operations we've learned in the past, in addition to what we've mentioned, are supported by a number of steps to repeat multiple operations, such as3dd
