推荐答案

如果您仅限于只是 cmd.exe，那么其他解决方案，尽管它们的大小，可能和你得到的一样好.但是，现代 Windows(例如您的 Win7)附带了很多其他工具，可以更轻松地完成工作.

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 yester.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)

然后你可以从你的 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 yesterday 变量将以 yyyymmdd 的形式创建，供您随意操作.

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