Command mode Press ":" Colon into extended mode

    W \ \ Save q \ \ exit Wq \ \ Save Exit q!  \ \ Force quit, do not save r filename \ \ read the file to the current file W filename \ \ Write the file to the specified file!command \ \ Execute the command r!command \ \    Read-in command output ①. Address delimitation start position, end position and operation such as 1y copy the first row 2,4d delete the second row to line fourth 2,+4y copy the second row to the sixth row. Represents the current line $ last line% full text, equivalent to 1,% start and end positions you can use regular expressions such as:/[0-9]/,/[0-9]/d \ \ To delete the first match to the containing number                   Rows to the second horse \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Match to a row containing a number the action command that can be used includes the D,y,w file (the rows within the range are stored as specified) r file \ \ (Inserts the specified file content at the specified location) ②. Find alternate find:/pattern down (pattern is what you're looking for)? pattern up find n,n with command in the same direction or in the opposite direction        Match (enter matching command and press n,n) to replace the format: s/find content/replace content/modifier find content can use patterns (regular) instead of using patterns but you can use a back reference, and you can use & to refer to the entire contents of the previous lookup         Modifier: I: Ignore case g: global substitution, by default each row replaces only the first occurrence of the GC: global substitution, replace before asking for a delimiter in the find replacement/can be replaced with the @ #等字符 For example: Delete the white space character from the beginning of the file: [EMAIL&NBSp;protected]^[[:space:]]\[email protected]@g Add a # 1,[email protected]^[[:space at the beginning of the file with all whitespace characters:  ]]@#\[email protected]
