一些零碎知识

%i是Windows命令行中用于循环的变量。在for命令中，%i代表从指定的文件列表中依次取出的每个文件的名称。例如，如果文件列表中有3个文件，分别为file1.txt、file2.txt和file3.txt，那么循环执行时，%i分别代表file1.txt、file2.txt和file3.txt。
%~ni 是 Windows 命令行中用于提取文件名部分的变量。其中 %i 是一个通配符，代表一个变量。在这个命令中，%i 代表了每个输入文件，而 %~ni 代表了 %i 变量中的文件名部分，其中 ~n 表示取文件名，i 是通配符变量的命名。

例如，如果 %i 是文件路径 C:\some\path\file.txt，那么 %~ni 就是 file。
