The "comm" approach expanded.

Code:
sort reham.txt > /tmp/reham.sor
sort reham1.txt > /tmp/reham1.sor
# Records in reham.sor but not in reham1.sor
comm -23 reham.sor reham1.sor
# Records in reham1.sor but not in reham.sor
comm -13 reham.sor reham1.sor

there is an option for "diff" to suppress blank lines... check the man page.
