Bat几个用法

2018年2月17日
| Windows

windows上cmd的几个命令用法：

1. 将memcached服务放进后台启动，这样会继续执行后边的命令(如果有)

start /b D:\memcached\memcached.exe

2. 暂停5秒，相当于linux的sleep

timeout 5

3. 打印时间戳

set d=%date:~0,10%

set t=%time:~0,8%

echo “curl_time: %d% %t%” >> C:\website_log.txt

4. 循环

:loop
执行的command
goto:loop

5. 还有手动刷新dns缓存

ipconfig/flushdns
