Do you mean that, if grep finds a match for a search term, you only want it to output the search term, not everything else on the line?
If so, either of these would work:
Code:
grep -o 'China' <filename> # would output just 'China' for each match
egrep -o '(China|Japan)' <filename> # similar, but matches either China or Japan
If you were thinking of something else, could you perhaps give a couple of examples
Perl
