Convert absolute path to relative path in batch file
是否可以将绝对路径转换为批处理文件中的相对路径？(与此相反)。显然，您需要两个输入：要转换的绝对路径，以及要将其相对化的绝对引用路径。
如：
1 2 3 | Path to convert: c:\documents\mynicefiles\afile.txt Reference path: c:\documents Result: mynicefiles\afile.txt |
1 2 3 4 5 6 | @echo off setlocal EnableDelayedExpansion set Path_to_convert=c:\documents\mynicefiles\afile.txt set Reference_path=c:\documents set Result=!Path_to_convert:*%Reference_path%\=! echo Result: %Result% |
如果您想从字符串的开头删除%cd%，这是另一个有效的方法。虽然速度很慢，但是如果情况允许，可以减少循环的数量。
