pgn-extract

A CLI program for manipulating PGN files

This is a command-line program for manipulating chess games recorded in the Portable Game Notation (PGN). Extracted games may be written out either including or excluding comments, NAGs, variations, move numbers, tags and/or results. Games may be given ECO classifications derived from the accompanying file /usr/share/pgn-extract/eco.pgn, or a customised version provided by the user. For a full description of pgn-extract's functionality see /usr/share/doc/packages/pgn-extract/help.html.
