  s: Represents a Replace operation
  %: "%": indicates the entire file. The symbol in front of s indicates the scope of the search, and the current line is omitted. such as: "1,20": means from line 1th to 20;
  /: delimiter, separating the source and target characters that need to be replaced, and the command
  ^H: Need to replace the content, this is a control character. ^h Input Method: Hold down the CTRL key first, then click the Letter V and the character H to complete the input
