Subject: unix tool for removing duplicates from a large .pgn file?
Hi,

I'm collecting as much chess matches played (by humans) as possible.
Now I have around 400MB of pgn-files and I would like to remove the
inevitable duplicates.
Does anyone know a tool for unix (linux/macos x/bsd/aix/etc.) doing so?

http://www.cs.kent.ac.uk/people/staff/djb/pgn-extract/

will do it for you. It has no GUI, will do what you want.

ChessDB (based on Scid, but developed further), will do too.

http://chessdb.sourceforge.net/

it has a GUI interface, so is quite different in use. Depends what you
want.
