  1. @echo off
  2. echo starttime,%time%
  3. echo starttime,%time%>timeresult.txt
  4. for /r %%i in (*.txt) do (
  5. echo %%~nxi
  6. call set t1=%%time%%
  7. echo waiting 3 second ...
  8. ping -n 3 127.1>nul
  9. call set t2=%%time%%
  10. call echo %%t1%%,%%t2%%
  11. call echo %%~nxi,%%t1%%,%%t2%%>>timeresult.txt
  12. )
  13. echo endtime,%time%>>timeresult.txt
  14. echo endtime,%time%
  15. echo complete

set t1, set t2 前不加call也试过了。
谢谢指点!
