将Powershell输出存储在CMD中的变量中

Question

In a batchfile, how do I store the output of a powershell command in a variable This isn't working

set yest=powershell get-date((get-date).addDays(-1)) -uformat "%Y%m%d"


powershell get-date((get-date).addDays(-1)) -uformat "%Y%m%d"

gives 20130623

set yest=powershell get-date((get-date).addDays(-1)) -uformat "%Y%m%d"
echo %yest%

gives powershell get-date((get-date).addDays(-1)) -uformat "md"

Answer 1

The closing braces and percent need to be escaped/doubled.

@echo off
for /f "delims=" %%a in ('powershell get-date((get-date^).addDays(-1^)^) -uformat "%%Y%%m%%d"') do set d8=%%a
echo %d8%
pause
