Batch recursing through folders & populating an array 1个
希望从特定点解析出路径&然后使用它来填充动态数组.
例:
Folder tree:
C:\Main\folder1
C:\Main\folder2\folder2-1
C:\Main\folder3\folder3-1\folder3-2
Desired result:
Array[1]=folder1
Array[2]=folder2
Array[3]=folder2\folder2-1
Array[4]=folder3
Array[5]=folder3\folder3-1\
Array[6]=folder3\folder3-1\folder3-2
这是下面的工作代码返回正常,但在完整路径中:
@echo off
setlocal EnableDelayedExpansion
SET folders=C:\Main
rem Populate the array with existent files in folder
set i=0
for /r "%folders%" /d %%a in (*) do (
set /A i+=1
set list[!i!]=%%a
)
set foldnum=%i%
rem Display array elements
for /L %%i in (1,1,%foldnum%) do (SET array[%%i]=!list[%%i]!)
for /F "tokens=2 delims==" %%f in ('set array[') do echo %%f
最佳答案 您将绝对路径传递给FOR循环.但即使使用相对路径,FOR循环也会做太多并将其转换为绝对路径.
这里的技巧是替换FOR循环中的绝对路径.
在实变量中创建循环变量的副本
set AA=%%a
然后在列表“array”中没有任何内容替换前缀反斜杠
set list[!i!]=!AA:%folders%\=!
完整的固定代码:
@echo off
setlocal EnableDelayedExpansion
SET folders=C:\Main
rem Populate the array with existent files in folder
set i=0
for /r "%folders%" /d %%a in (*) do (
set /A i+=1
rem create a copy of the loop variable in a real variable
set AA=%%a
rem replace prefix+backslash by nothing in a the list "array"
set list[!i!]=!AA:%folders%\=!
)
set foldnum=%i%
rem Display array elements
for /L %%i in (1,1,%foldnum%) do (SET array[%%i]=!list[%%i]!)
for /F "tokens=2 delims==" %%f in ('set array[') do echo %%f
然后你以相对的方式获得%folders%的所有目录.
