[文本处理] 【已解决】批处理如何全盘搜索获得DLL的详细路径

luckboy45

我有如下内容的list.txt

dl_peer_id.dll
dl_uac_tool.dll
DocShare.dll
download_engine.dll
down_dispatcher.dll
dphubt.dll
DWFShellExtension.dll

是获取的DLL名称，如何全盘搜索以上DLL，并获得其详细路径，最终输出成list1.txt，内容如下示意。

C:\WINDOWS\system32\down_dispatcher.dll
C:\WINDOWS\system32\CustomFace.dll
C:\WINDOWS\system32\dphubt.dll
C:\Program Files\ATI Technologies\DWFShellExtension.dll
D:\123\down_dispatcher.dll

目前我已经有多个方法获取DLL，只是多一种思路而已。再次感谢各位的帮助！~

最近跟了楼主几个帖子，核心诉求就是要获取 *.dll 文件的全路径，已知有 msinfo/powershell/wmic 这些针对性方法，为何还要用最原始的 dir/b/s 全盘搜索呢？

@echo off
cd /d "%~dp0"
(for /f "delims=:" %%i in ('wmic logicaldisk get name ^| find ":"') do (
	2>nul dir /b /s /a-d "%%i:\*.dll" | findstr /lig:"list.txt"
	2>nul dir /b /s /a-d "%%i:\windows\*.dll" | findstr /lig:"list.txt"
)) > "out.txt"
pause

感谢你的热情帮助！代码运行提示“findstr无法打开list.txt”

问题应该出在DIR没有成功输出，即单独用(dir /b/s/a-d C:\abseil_dll.dll)>1.txt，能实现输出完整路径

于是修改成这样实现了详细路径的输出

setlocal enabledelayedexpansion &set "s=" &cd.>list1.txt
for /f "delims=" %%a in (list.txt) do (set s=!s! "%%a")
for %%d in ("c:\", "d:\", "e:\") do (
  cd /d %%d &(dir /b/s/a-d !s!)
)>>list1.txt

代码第三行设置要搜索多少个盘符根目录
假设 list.txt 总字符量不超过 8100 个字符 》为尽量提升 dir/b/s 一次性全盘搜索效率须尽量用满其命令行参数空间

@echo off &setlocal enabledelayedexpansion &set "s=" &cd.>list1.txt
for /f "delims=" %%a in (list.txt) do (set s=!s! "%%~nxa")
for %%d in ("c:\", "d:\", "e:\") do (
   cd /d %%d &dir /b/s/a-d !s!>>"list1.txt"
   set "s=" &(for /f "delims=" %%a in (list1.txt) do echo,%%~nxa)>"0.0"
   for /f "delims=" %%a in ('findstr /ivg:"0.0" list.txt') do (set s=!s! "%%a")
   if not defined s goto[end]
)
:[end]
del/q "0.0"&endlocal&pause&exit/b
