Difficult sed/awk question

I'm wanting to search a text file for a phrase. If it finds this phrase then it will return the line number that the phrase exists at. Is this possible?

Once I've found the line the phrase is on I then need to alter the text. I know I can just search for phrase and edit that but I also need the line number that it was originally at for another purpose.

Way #1)
grep -in "phrase" filename.txt

-i = ignore case (maybe not needed)
-n = line number.

Way #2)
vi filename.txt
then /"phrase"
look in corner for line number.

Please use more descriptive topics. "searching for strings, how to output line number(s)?" would be a much better topic--we'd know what your problem is about.

Also, difficulty is relative--I find playing the tuba and driving cars difficult, but I know of at least one person who finds it a lot easier than I do. So saying "difficult" in the subject line is only informative to people who now what you find difficult.
