If your grep does not have -o etc. and this is regarding to your former post https://www.unix.com/shell-programmin...g-problem.html, you can also just slightly modify the line I already gave in the there to get only the matches in the files, not the complete files as output:

Code:
$> cat file1
eins
zwei
OCT
drei
vier
$> cat file2

affcat

AFCAT(1)						      General Commands Manual							  AFCAT(1)

NAME

       afcat - Output contents of an image file to stdout.

SYNOPSIS

       afcat [options] image [images]

DESCRIPTION

       affcat  outputs the contents of an image file to stdout.  Image files that are not raw but are recognized by AFF will be output in raw for-
       mat. Missing pages will not be padded, but the fact that they are missing will be noted on STDERR.

       The options are as follows:

       -s name
	      Output the named segment, instead of the image data. This is a way to output metadata.

       -p nnn Just output page number nnn

       -S nnn Just output data sector number nnn.  Sector #0 is the first sector.

       -q     Quiet mode. Don't print to STDERR if a page is skipped because it is not present.

       -n     Noisy mode. Tell when pages are skipped.

       -l     List all the segment names, rather than outputing data.

       -L     List Long. Prints segment names, lengths, and args.

       -d     Debug mode. Print the page numbers to stderr as data goes to stdout.

       -b     Output BADFALG for bad blocks (default is to output NULLs).

       -v     Just print the version number and exit.

       -r offset:count
	      Seek to the given byte offset and output count characters in each file; may be repeated.

HISTORY

       afcat first appeared in AFFLIB v1.00.
