echo 如何换行？

echo 怎么换行？？？？？？？？

JScript code

echo del d:\database\kup.bak  set /a StartS=%time:~6,2% set /a StartM=%time:~3,2%  set /a StartH=%time:~0,2% >test.txt输出后看到test.txt显示这样的格式del d:\database\kup.bakset /a StartS=%time:~6,2% set /a StartM=%time:~3,2% set /a StartH=%time:~0,2%

BatchFile code

(    echo del d:\database\kup.bak    echo set /a StartS=%%time:~6,2%%    echo set /a StartM=%%time:~3,2%%    echo set /a StartH=%%time:~0,2%%)>test.txt

老老实实的该用几个echo就用几个，瞎折腾这个有啥用？
