[文本处理] 批处理findstr排除文本,文本文件内容为空会出错

  1. for /f "delims=" %%i in ('findstr /g:black_list.txt /v list.txt 2^>nul') do (
  2. echo %%b\Bin\x64\DISM10\dism.exe /image:%%b /Remove-Capability /CapabilityName:"%%i"
  3. %%b\Bin\x64\DISM10\dism.exe /image:%%b\Mount\Install /Remove-Capability /CapabilityName:"%%i"
复制代码
black_list.txt 内容为空,就失效了
怎么解决呢,

虽然black_list.txt随便写点就解决了,但这bat不完美

回复 1# hentai87


在for命令上面加一句:
  1. more "black_list.txt" | findstr "." >nul 2>&1 || goto :eof
