I will try to explain with following example.


original_file
Code:
a@b.com
c@d.com
E@f.com
g@h.com
i@j.com
k@l.com

change_file
Code:
c@d.com
i@j.com

I want to change the contents of original_file that matches contents of change_file with specific text like x@x.com
After running the query the resulting file should look like following

New_file
Code:
a@b.com
x@x.com
E@f.com
g@h.com
x@x.com
k@l.com

I hope this explains my requirement. Thanks alot for all the support.
