Liunx Vim commands Edit file contents

Sometimes the project has been deployed in Tomcat, but you need to modify some of the contents of the configuration file or modify the content of a JSP file, you will think of the local modified files uploaded to the server and then replace it, in fact, you can use the VIM command directly edit the good ...

Here's an example ↓

Create a file in a folder first

Here I first created a test folder with the MkDir command, and then created a a.txt file with the vim a.txt command in the Test folder. You'll find that after you've implemented Vim A.txt, you'll be the following ↓

This time you press the I key to open the insert and then enter the text on the line.

Press ESC to exit Edit state after you enter, and then the last row type: wq! Save exit

Then enter the cat command to view the A.txt file and you will see the contents of the file you edited.
