Batch file new line problems

由 空扰寡人 提交于 2019-12-24 12:43:56
问题 I'm tearing my hair out now.

It is vitally important that each line of every file created is separated by a blank line. This is why I have included the "Echo." lines. See batch file code below: pushd \\SRVAPP1\Image Archive Echo %CD% PAUSE for /R %CD% %%F in (*.jpg) do ( Echo %%~nF Echo. Echo ^<html^>^<img src='^.%%
