 6 echo start=%startime% >> d:/pinglog/ptest01.txt
 7 ping 192.168.1.133 >> d:/pinglog/ptest01.txt
 8 set endtime=%DATE%%time%
 9 echo end=%endtime% >> d:/pinglog/ptest01.txt
10 echo /n >> d:/pinglog/ptest01.txt
11 echo -------------------------------------------- >> d:/pinglog/ptest01.txt

字符串操作：
截取字符串：

@echo off
set abc=hello world, this string come from bat
echo 原字符串为:%abc%
echo 截取前5个字符:%abc:~0,5%
echo 截取最后5个字符:%abc:~-5%
echo 截取第一个到倒数第6个字符:%abc:~1,-5%
echo 从第4个字符开始截取5个字符:%abc:~3,5%
echo 从倒数第14个字符开始截取5个字符:%abc:~-14,5%
