Multi File processing


I have 2 csv files:


Using the ksh, I'm reading by line and grabbing the value in the 2nd column ($2). I want to use this value and search the second file to find a line with a match. If it is found I want to grab the value of column 1 ($1) of the second file during that read

while readline
    if test $i -ge 1;
        echo "$line" awk '{print $1","$2}' >> File3 

        now use $2 to search File2 for a match
        if found print the value of $1 in File2 to File3    fi
 done < $File1


Can anyone give me some insight as to how this can be done?
