The previous two messages provide examples of code to find your lines from the file. The other issue that sometimes is a problem is in finding the number 17 since it can be part of 617 and 179. Thus, you may need to modify the grep for this to one of the following:
" 17 "
"17 "
" 17"

Depending on where you expect the 17 to be on the line, you might want to force a space character before/after or both.
