批处理中使用 日期时间 作为文件名的方法

set    CurrentDate=%date:~0,10%
set    CurrentYear=%date:~0,4%
set    CurrentMonth=%date:~5,2%
set    CurrentDay=%date:~8,2%
set    CurrentTime=%time%
set    CurrentHour=%CurrentTime:~0,2%
if    /i %CurrentHour% LSS 10 (set CurrentHour=0%CurrentTime:~1,1%)
set    CurrentMinute=%time:~3,2%
set    CurrentSecond=%CurrentTime:~6,2%
set    CurrentDateTime=%CurrentYear%_%CurrentMonth%_%CurrentDay%_%CurrentHour%_%CurrentMinute%_%CurrentSecond%
set    log_file=c:\gminer-%CurrentDateTime%.log

log_file 里面装的就是文件名及路径，使用的时候这样用 %log_file%
例如 echo %log_file%
