Try this, it shows only different records.

Code:
sdiff file1 file2 | grep "|"

does something like this work for you?
Code:
diff file1 file2 | egrep "[<|>]"

If you are prepared to sort both files first, take a look at the unix "comm" command.

The "diff" command is unsuitable if you only need the differences because it shows the difference in context and therefore includes lines which are not different.

Another method: Print lines which are not common. This is less thorough than using "comm" and assumes that there are no duplicate differences.

Code:
cat reham.txt reham1.txt | sort | uniq -u

Code:
$ diff reham.txt reham1.txt | egrep "[<|>]"
<
<
< reham     2/5/2011               $20,000
> reham      2/5/2010                  $20,000
<
<

> hany       4/4/1989               $100,000

I really don't need to this empty rows between them
