問題描述

Windows 批處理腳本：Findstr 輸出：過濾子字符串 (Windows batch script : Findstr output : Filter substring)

我有一個腳本：

C:\"Program Files (x86)"\Dell\"Command Configure"\X86_64\cctk advsm ‑‑report=All | findstr /c:"Current speed" >> %LOG_FILE_NAME%

給出以下輸出：

Current speed                : 3101 rpm

我只需要實際值“3101” 不是整條線。我怎樣才能得到這個？

參考解法

方法 1:

for loops are used for this:

for /f "tokens=3* delims=: " %%i in ('"%programfiles(x86)%\Dell\Command Configure\X86_64\cctk" advsm ‑‑report=All ^| findstr "Current speed"') do (echo %%i)>>%LOG_FILE_NAME%

方法 2:

Untested idea, but perhaps it would be simpler still if you just report the value you want in the first place!

@For /F "Tokens=4" %%G In ('^""%ProgramFiles(x86)%\Dell\Command Configure\x86_64\cctk.exe" Advsm ‑‑Report^=C^"') Do >>"%LOG_FILE_NAME%" @Echo %%G

If C doesn't output what you want then you'd have to use Report=All and search for your line. You can use find.exe for that:

@For /F "Tokens=4" %%G In ('^""%ProgramFiles(x86)%\Dell\Command Configure\x86_64\cctk.exe" Advsm ‑‑Report^=All ^| %SystemRoot%\System32\find.exe "Current speed"^"') Do >>"%LOG_FILE_NAME%" @Echo %%G
