同时批量搜索多个字符串

Question

我有这么大的设备数据库：

Equipment500
Equipment501
..........
Equipment998
Equipment999

以及包含设备详细信息的更大数据库：

Equipment1:details....
Equipment2:details....
..................
Equipment9998:details....
Equipment9999:details....

我需要的是 select 我需要的设备的详细信息：

for /f "tokens=* delims= " %%a in (%cd%\equipment.db) do (
findstr /i /c:"%%a" details.db > Output\%%a
)

输出当然是一个包含文件的文件夹：

In Equipment500 it will be Equipment500:details....
In Equipment501 it will be Equipment501:details....
..................
In Equipment998 it will be Equipment998:details....
In Equipment999 it will be Equipment999:details....

问题是要花很多时间。

我需要这个多线程，以便它同时运行更多的 findstr 实例（最好是全部 500 个）以立即进行处理。

任何想法表示赞赏。谢谢！

Answer 1

@echo off
echo building input files (this needs some time):
del *.db
for /l %%i in (500,1,999) do @echo Equipment%%i>>equipment.db
for /l %%i in (1,1,9999) do @echo Equipment%%i:Detailswhatever>>details.db

echo %time% start adapting
REM adapt equipment.db:
(for /f "delims=" %%i in (equipment.db) do echo %%i:)>equip.db

REM find all strings:
echo %time% start searching
findstr /g:equip.db details.db >output.txt
echo %time% done

注意："Equipment.db" 必须进行调整，因为搜索 "Equipment2" 也会找到 "Equipment20"，Equipment21"... "Equipment200" ...

Answer 2

由于您只提供有关文件结构的模糊信息，我建议

@echo off
for /f "tokens=1*delims=:" %%a in (details.db) do >>%%a.dat echo %%b

假设 details.db 中的每个条目都是

的形式

equipment1234:details
