我想为变量中提供的每个路径执行一些for循环。 echo !temp!
工作正常,但是下面的for命令无法正常工作:
@echo off
setlocal enabledelayedexpansion
set paths=(C:\test C:\test2)
for %%p in %paths% do (
set temp=%%p
echo !temp!
for /r !temp! %%f in (*.h) do (echo %%f)
for /r !temp! %%g in (*.h *.cpp) do (echo %%g)
)
答案 0 :(得分:3)
在所有for
commands语法模式中:
FOR %%parameter IN (set) DO command
FOR /R [[drive:]path] %%parameter IN (set) DO command
FOR /D %%parameter IN (folder_set) DO command
FOR /L %%parameter IN (start,step,end) DO command
FOR /F ["options"] %%parameter IN (filenameset) DO command
FOR /F ["options"] %%parameter IN ("Text string to process") DO command
FOR /F ["options"] %%parameter IN ('command to process') DO command
在%%parameter
之前的所有文本都应在第一个解析阶段中知道。阅读How does the Windows Command Interpreter (CMD.EXE) parse scripts?。
但是,下一个脚本应该按预期工作
@ECHO OFF
SETLOCAL EnableExtensions EnableDelayedExpansion
set "paths=(C:\test C:\test2)"
for %%p in %paths% do (
set "temp=%%~p"
echo !temp!
call :doit
)
rem skip procedure
goto :domore
:doit
for /r "%temp%" %%f in (*.h) do (echo %%f)
for /r "%temp%" %%g in (*.h *.cpp) do (echo %%g)
goto :eof
:domore
