Kharen,

Ok, this should work:
Code:
#!/bin/sh

while read line ; do
        [ -z "`echo $line | awk '{print $3}'`" ] && continue
        [ -z "`echo $line | tr ' ' '\n' | uniq -d`" ] && echo $line | awk '{print $1}'
done < "$1"

Note: I am assuming that the columns in the file are seperated by a single space (not tab).
