问题是俺每次

$ zhmark2en ./ md

这样运行后,都产生一大堆 *.mdg 文件,内容是原始文件

参考:
mac os 中用 sed 命令 替换文本中的指定内容

为毛?!

probelm is running:

$ zhmark2en ./ md

will gen. *.mdg files, content originality files

so i just want replace somethin just in originality files.
not need backup.

其实就是不认真问 man 的原因!

 -i extension
         Edit files in-place, saving backups with the specified extension.  If a zero-length extension is given, no backup
         will be saved.  It is not recommended to give a zero-length extension when in-place editing files, as you risk
         corruption or partial content in situations where disk space is exhausted, etc.

关键就是那个 zero-length 在bsd样的 sed 中要表述为

sed -i "" "s/。/. /g;...

俺又一次 #图样图森破 了...

其实弯角引号/撇号、HORIZONTAL ELLIPSIS（半个中文省略号）和 EM DASH（半个中文破折号）在英文里也使用的呀…
