So to clarify, you are wanting to only match lines that have (for example) 'kim' in the first or second field, but display the entire line where it's matched, right?
If so, you'll need a little bit of logic around the grep:
Code:
while read line ; do if echo $line | cut -d ' ' -f 1,2 | grep kim > /dev/null ; then echo $line ; fi ; done
