[Nitro] question for unix wizzards

[George Moschovitis]

Dear devs,

2 small unix related questions.

does anyone know about:

- a quick and easy way to remove duplicate lines from a text files?
- a quick and easy way to decide if two image (binary) files are the same
image/picture?

thanks in advance for your help!
