推荐答案

如果你只限于 em> cmd.exe ，那么其他的解决方案，尽管他们的大小，可能会很好，你会得到。然而，现代Windows（如Win7）附带了相当多的其他工具，可以使工作更容易。

If you're limited to just cmd.exe, then the other solutions, despite their size, are probably as good as you'll get. However, modern Windows (such as your Win7) ships with quite a few other tools which can do the job far easier.

只需创建一个VBScript yesterday.vbs 脚本如下：

Just create a VBScript yester.vbs script as follows:

d = date() - 1
wscript.echo year(d) * 10000 + month(d) * 100 + day(d)

然后，您可以从 cmd 脚本中调用它：

Then you can call it from your cmd script with:

for /f %%a in ('cscript //nologo yester.vbs') do set yesterday=%%a

和昨天变量将以 yyyymmdd 的形式创建，以便您操作你愿意。

and the yesterday variable will be created in the form yyyymmdd for you to manipulate however you desire.
