I want to delete the contents of a file which are matching with contents of other file

Hi,

I want to delete the contents of a file which are matching with contents of other file in shell scripting.
Ex.
file1
Code:
sheel,sumit,1,2,3,4,5,6,7,8
sumit,rana,2,3,4,5,6,7,8,9
grade,pass,2,3,4,5,6,232,1,1
name,sur,33,1,4,12,3,5,6,8
sheel,pass,2,3,4,5,6,232,1,1

File2
Code:
grade,pass,2,3,4,5,6,232,1,1
sheel,pass,2,3,4,5,6,232,1,1


so i want to delete contents of file 1 by reading line by line from file2
Could any one please suggest as i need urgent help on this.

Thanks in Advance!!!!!

if it is about removing lines from one file which are there in another file comm command can help you, bit it works on sorted files. read 'man comm' to check

Thanks itkamaraj for help, i found the answer and both comm and diff commands can be used for this purpose with combination of grep. Thanks to sharadpisal also.
