Reading n number of lines after finding string
I am trying to search a file for a value: "Top 30 reject reasons" and want the next 30 lines after that and output in a text file.

If I knew the line number, I can use a combination of head and tail commands to get my results, but this doesn't seem to work when I don't have a line number.

I tried
Code:
grep "Top 30 reject reasons:" a11.txt | head -n30

but that didn't seem to help.

Oh, and this is across multiple files - if you can figure something that will help with this, amazing! Otherwise I can make it into a script and run that!
