wgs2sgf需要处理二进制文件，以前一直在windows下用UltraEdit，无法复制文本，有点不方便。今天搜了一下linux下的类似工具，看到了xxd。在windows下可以通过msys使用xxd。下面就以msys中的xxd为例。

$ xxd --help Usage: xxd [options] [infile [outfile]] or xxd -r [-s [-]offset] [-c cols] [-ps] [infile [outfile]] Options: -a toggle autoskip: A single '*' replaces nul-lines. Default off. -b binary digit dump (incompatible with -ps,-i,-r). Default hex. -c cols format <cols> octets per line. Default 16 (-i: 12, -ps: 30). -E show characters in EBCDIC. Default ASCII. -g number of octets per group in normal output. Default 2. -h print this summary. -i output in C include file style. -l len stop after <len> octets. -ps output in postscript plain hexdump style. -r reverse operation: convert (or patch) hexdump into binary. -r -s off revert with <off> added to file positions found in hexdump. -s [+][-]seek start at <seek> bytes abs. (or +: rel.) infile offset. -u use upper case hex letters. -v show version: "xxd V1.10 27oct98 by Juergen Weigert". |
使用示例
处理对象是wgs棋谱，棋谱信息头有122字节，由于wgs中有单字节表示的信息，希望1字节1组。执行以下命令：

1 2 3 4 5 6 7 8 9 |
$ xxd -g 1 -l 122 wgsfile.wgs 0000000: 02 00 00 00 31 59 2c 4f 00 00 c3 fb d7 d6 b6 bc ....1Y,O........ 0000010: b1 bb c6 f0 b9 e2 c1 cb 00 00 00 00 00 00 00 00 ................ 0000020: 10 00 00 00 00 00 00 00 46 00 00 00 00 00 00 00 ........F....... 0000030: 00 00 00 00 2e 87 3b 2f 54 00 6a 6b 6c 00 00 00 ......;/T.jkl... 0000040: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0000050: 10 00 00 00 4b ff ff ff 4d 00 00 00 00 00 00 00 ....K...M....... 0000060: 00 00 00 00 00 13 00 07 05 08 01 00 00 00 00 00 ................ 0000070: 00 00 00 00 00 00 00 00 07 01 .......... |
和UltraEdit显示类似，只是中文字符没显示出来。不过已经解读过的信息就无所谓了。
