Vim commands in linux

Some advanced editors will contain macro functions, which are certainly not missing in vim. It is very convenient to use Macros in vim:

: Qx starts to record macros and saves the results to register x
Q exit record mode
@ X macro commands for playing records in the x register
After you enter qx in normal mode, all the edits to the text will be recorded. If you enter q again, the record mode will be exited.
And then input @ x to repeat the recorded command. This command can be followed by a number to indicate the number of times to repeat. For example, @ x20 can be repeat 20 times. This is very useful in text batch processing.
Edit multiple files at the same time
Among the many vim plug-ins, there is a plug-in called minibuffer, which is called the tab function below. You can edit multiple files at the same time.
Tag command

: Tabe fn: edit the file fn in a new tab
Gt switch to the next tab
GT switch to the previous Tab
: Tabr switch to the first tab
: Tabl switch to the last tab
: Tabm [N] Move the current tab to the nth tab
Yes, as you think, it is similar to eclipse, ue, and other tabs!
Window command
Ctrl + w s Horizontal Split Window
Ctrl + w switch window
Ctrl + w q exit the current window (because there are multiple files at the same time, this command will not affect other Windows)
Ctrl + w v Vertical Split Window
Others
Vim does not make actual changes to the file before saving, but only loads the file into the buffer. The editing of the file is actually the editing of the buffer. It will not be saved to the physical file until: w.

: E file: load the file to the new buffer.
: Bn jump to the next Buffer
: Bd Delete buffer (close file)
: Sp fn split the window and load fn to the new window
Exit Editor

: W write the buffer to a file, that is, save the modification.
: Wq: Save the modification and exit.
: X Save the modification and exit
: Q exits. If the buffer is modified, a message is displayed.
: Q! Force exit, discard Modification
Search and replace
/Pattern: returns the string pattern.
? Pattern: returns the string pattern.
N: Next match (If yes/search, it is the next one ,? Search to the next one)
N match (same as above)
: % S/old/new/g search the entire file and replace all old with new
: % S/old/new/gc search for the entire file, replace all old with new, and each time you want to confirm whether to replace
Copy and paste
Dd deletes the row where the cursor is located.
Dw deletes a word)
X Delete the current character

D. Delete it to the end of the row.
Yy: copy a row. The command can be followed by a number to identify multiple rows. For example, 6yy indicates that six rows are copied from the current row.
Copy one word from yw
Y $ copy to the end of the row
P paste the clipboard content to the current row
P paste the clipboard content to the current row
] P is indented and vim automatically adjusts the code indent.
"A puts the content into/into register a, and supports multiple clipboard
Note: for example, a commonly used register is a system register with the name +. Therefore, the "+ p" command is pasted from the system clipboard to vim. Note that the "+" operator is not represented here, 21 registers.
Move cursor
