How to avoid duplicates with GnuSort ?

[Peter Steiner]

Hello,

I downloaded the gnu tools archive

txt20b.zip from http://www.delorie.com/pub/djgpp/current/v2gnu/
and tried to use the sort.exe inside.

However I did not found a "avoid duplicates" option for the sort command.

Is there such an option ?
Or is there a newer version of the sort ?

Thank you for the answer

Peter
