How do I replace a line in a text file with a new line?

Assume I've opened the file and have every line in an array of string objects i'm now looping through

//find line with ']'
    for i, line := range lines {

        if strings.Contains(line, ']') {


            //replace line with "LOL"
            ?
        }
    }
