You can use complicated regular expression to match the lines. Using v instead of g will negate the pattern. So, to delete lines that do not have the word ‘saloon’, you will If you want to delete that do not match a specific pattern, then you will need to negate the match before deleting. delete lines that do not match the pattern The search is case-sensitive by default and this will delete all the lines that match the search pattern specified in the command. So, if you want to delete all lines in the file that contain the word ‘ saloon‘, then You can also do a search and delete, if you want to delete lines that contain certain words or character sequences. delete lines that match a pattern in vi or vim editor ![]() To delete all lines including the current line, do not add the 1.
