Common VI operations

I have been using VI for a short time. I didn't intentionally learn VI command usage, but I got familiar with it when I was using it. Although it was slow, I remember it quite well, write down the commands I have mastered.

 

1. delete operation

X delete a single character at the cursor

Dd deletes the row where the cursor is located.
DW deletes all characters from the current character to the end of a word including Spaces
# X for example, 3x Delete the three characters to the right of the cursor
# Dd For example, 3DD deletes three lines of text from the current row

 

2. Cancel the operation
U command to cancel the last operation, you can use multiple times to restore the original operation
U cancel all operations
CTRL + R can be used to restore operations using the U command

 

3. copy operation
Run the YY command to copy the entire line to the VI buffer.
YW copies the content from the current cursor position to the end of the word to the VI cache, which is equivalent to copying a word.
Y $ copy the cursor to the cache area at the end of the row
Y ^ copy the cursor to the cache area from the beginning of the line
# Yy. For example, 5yy means copying 5 rows.
# YW: for example, 2yw means copying two words.
If you want to copy the content between Row M and row N, you can enter m in the last row mode. For example, NY: 3, 5y copies the content from row 3 to row 5 to the cache area.

 

4. Paste

P

 

 

The new commands will be supplemented later.
