Question about GREP
I have 2 files, in one file is a list of hex numbers, the other is what i need matched. Is it possible for me to specify to grep the list and have it go through the second file for each item in the list in the first file to match the lines? so this is like a cross-refference.

Code:
grep -f file_with_hex_list file_to_be_matched

is that the exact command? say "hexlist" is the list file and "searchlist" is the search file, i typed:

Code:
grep -f hexlist searchlist > results

all it did was copy searchlist to results.

Then all the lines in searchlist file should contain any one of hex numbers in hexlist file.

no - the whole file does not match the list.
