how to save a file in vim code example

Example 1: how to insert in vim and save

vim filename #open file in vim
//To insert text press i and you can start editing
//Press Esc key and type :wq to save a file AND exit
//Press Esc key and type :w to save WITHOUT exiting

Example 2: exiting vim

Press Esc key: This is very important, because you must exit the edit mode first before typing the exit command(s). Next, you can type one of the following commands:
:q (yes, the colon is included in the command) – This will quit the editor
:q! – Quit Vim without saving the data file
:wq – Save the file and exit Vim
And then press the Enter key

Example 3: vim save file

// Save a new file (if you have entered vim without first creating a file)
:w <filename>
// Save file and exit
:x
