last occurrence of a match through multiple files
Hi all,
I have a lot of files with extension ".o" and I would like to extract the 10th line after (last) occurrence of a given string in each of the files.

I tried:

Code:
$ grep "string_to_look_for"  *.o -A 10 | tail -1

but it gives the occurrence in the last file with extension .o

Code:
zNaI14dA-volume0231941.o-      total      8.22863E-05 0.0075

Any idea how to do the job?
Thank you,
Sarah

Try
Code:
for i in *.o
do
   grep "string_to_look_for" "$i" .....
done
