so i kinda cheated, i have an awk script that turns a header row into 1 column with the fields as rows, and i ran that on each file in the dir, the painful brute squad, i probably could have put it in a do loop, oh well

then i ran

 find . -type f -name '*.txt' | xargs grep -i -o -n "what_im_looking_for" > outfile.out
the out file wasn't cinderella pretty but nice enough, when i get a new set of files and a new dir, ut'oh, i'll have to run the brute squad again

for f in *.txt; do head -10 $f > /directory/$f; done
grep -n -b -m 1 -w ".*im_looking.*" /directory/*.txt > oufile.out
The first line is a for ; do ; done loop.
The f in *.txt creates a list of filenames ending with .txt in the current directory and each filename is assigned in turn to the variable f on each pass through the loop. The head -10 $f reads the first ten lines in the file with the filename in the variable f. The > /directory/$f sends (redirects) the lines that were read to a file with the same name in another directory. You need to supply an appropriate directory name.
The second line searches for whole words containing the string im_looking in the newly created files. The > oufile.out sends (redirects) the results of the search to the file outfile.out in the current directory.
