PGN-EXTRACT(1)
NAME
pgn-extract - a Portable Game Notation (PGN) extractor
SYNOPSIS
pgn-extract [flags] file.pgn [file.pgn ...]
DESCRIPTION
This manual page briefly documents pgn-extract. This manual page was
written for the Debian GNU/Linux distribution because the original program does not have a manual page.
OPTIONS
- -7 Output the seven tag roster for each game. Other tags,
- apart from FEN and possible ECo/Opening/Variation) are lost.
- -aoutputfile
- The file to which extracted games are to be appended. See -o flag for overwriting an existing file.
- -Aargsfile Read the program's arguments from argsfile.
- -b[elu]num Restricted bounds on the number of moves in a game; lnum
- set a lower bound of `num' moves, unum set an upper bound of `num' moves, otherwise num (or enum) means equal-to `num' moves.
- -cfile[.pgn]
- Use file as a list of check files for duplicates.
- -C Don't include comments in the output. Ordinarily these are
- retained.
- -dduplicatefile
- The file to which duplicate extracted games are to be written.
- -D Don't output duplicate extracted game scores.
- -eECO_file Perform ECO classification of games. The optional ECO_file
- should contain a PGN format list of ECO lines. Default is to use /usr/share/pgn-extract/eco.pgn as ECO_file.
- -E[123] Split output into separate files according to ECO. E1: Pro
- duce files from ECO letter, A.pgn, B.pgn, etc. E2: Produce files from ECO letter and first digit, A0.pgn, etc. E3: Produce files from full ECO code, A00.pgn, A01.pgn, etc. All files are opened in append mode.
- -ffile_list The file file_list contains the list of PGN files to be
- searched - one per line.
- -F Output a FEN string comment of the final game position.
- -h Print an abbreviated list of help.
- -h1 Print further help.
- -? Print an abbreviated list of help.
- -llogfile Create a new logfile for the diagnostics rather than using
- stderr.
- -Llogfile Append all diagnostics to logfile rather than using stderr.
- -noutputfile
- Write all valid games not otherwise output to outputfile.
- -N Don't include NAGs in the output. Ordinarily these are
- retained.
- -ooutputfile
- The file to which extracted games are to be written. Any existing contents of the file are lost (see -a flag).
- -P Don't match permutations of the textual variations (-v).
- -r Report any errors but don't extract.
- -Rtagorder Use the tag ordering specified in the file tagorder.
- -s Silent mode don't report each game as it is extracted.
- -S Use a simple soundex algorithm for tag matches. If used,
- this option must precede the -t or -T options.
- -ttagfile File of player, date, or result, extraction criteria.
- -Tcriterion Player, date, or result, extraction criteria.
- -U Don't output games that only occur once. (Use with -d to
- identify duplicates in multiple files.)
- -vvariations
- The file variations contains the textual lines of interest.
- -V Don't include variations in the output. Ordinarily these
- are retained.
- -wwidth Set width as an approximate line width for output.
- -W Don't rewrite the moves into Standard Algebraic Notation.
- -W[cm|epd|san|elalg|lalg|halg]
- Specify the output format to use. Default is san: standard algebraic notation. cm is ChessMaster format. epd is EPD format. lalg is long algebraic. halg is hyphenated long algebraic. elalg is enhanced long algebraic. Use -Wsan[PNBRQK] for language specific output, e.g., use -WsanBSLTDK for German. Similarly for -Welalg[PNBRQK].
- -xvariations
- The file variations contains the lines resulting in positions of interest.
- -zendings The file endings contains the end positions of interest.
- -Z Use the file virtual.tmp as an external hash table for
- duplicates. Use when MallocOrDie messages occur with big datasets.
- -#num Output num games per file, to files named 1.pgn, 2.pgn,
- etc.
