Adding the names of frequent contributors as tags only proves you have seen several questions, which means you should know how to write a complete question. It generally does not attract actual attention.

Try this:
- Read in the whole text file
- Split it on \r?\n to break it in to lines
- Now you have an array of lines, so you can edit line(i) to modify just the i-th line
- Use strrep or regexprep to modify the contents of that line
- Use strjoin() to join all the lines back together into a single string
- Write that string out to your new file
