I want to write a shell script to compare two .csv files. First one contains filename,path the second .csv file contains filename,paht,target. Now, I want to compare the two .csv files and output the target name where the file from the first .csv exists in the second .csv file.

Ex.

a.csv

build.xml,/home/build/NUOP/project1  
eesX.java,/home/build/adm/acl

b.csv

build.xml,/home/build/NUOP/project1,M1
eesX.java,/home/build/adm/acl,M2
ddexse3.htm,/home/class/adm/33eFg

I want the output to be something like this.

M1 and M2

Please help Thanks,
