Are these real world examples, or are they going to be text files with any amount of data, words, spaces, commas, other characters potentially on the line. Same for the list of lines to check?
Are there any blank lines etc. in the file that are important?
And just to check it seems you are checking the whole line to comment, i.e. if your string was found part way across the line.
If all of those end up being just like your answer it is a relatively simple for loop but no point writing that if not.
thanks
