dos延时处理命令（DOS delay processing command） 1, pause (Pause), delay (Delay), wait (Wait), sleep (Sleep) 1) for+set+if, time accuracy of 0.01 seconds, applicable platform for WinNT/2K/XP/2003. For uses analytic variables%time% to coexist for two time points,%start% and%now%, and then uses set /a to calculate the time difference between the two time points, and finally uses if to determine whether the time difference has reached the set pause time. CODE: -------------------------------------------------------------------------------- @echo off SETLOCAL enableextensions Echo%time% Call: ProcDelay 200 Echo%time% Goto: EOF : ProcDelay delayMSec_ SETLOCAL enableextensions For /f tokens=1-4 delims=:%%h, in (%time%), do, set, start_=%%h%%i%%j%%k : _procwaitloop For /f tokens=1-4 delims=:%%h, in (%time%), do, set, now_=%%h%%i%%j%%k Set /a diff_=%now_%-%start_% If,%diff_%, LSS,%1, goto, _procwaitloop Endlocal goto: EOF 2) VBS script in the sleep function, time accuracy of 0.001 seconds, using the platform for the Win9x/WinNT series. Dynamically create a VBS script that calls the sleep () function, and then call it with the command line version cscript of the Windows script host. CODE: -------------------------------------------------------------------------------- @echo off SETLOCAL enableextensions enabledelayedexpansion Echo WScript.Sleep 2000 %temp%\tmp$$$.vbs Echo%time% Cscript //nologo%temp%\tmp$$$.vbs Echo%time% For,%%f, in (%temp%\tmp$$$.vbs), do, if, exist,%%f, del,%%f Endlocal goto: EOF 3) Ping messaging interval, time accuracy of 1 second, using the platform for the Win9x/WinNT series. Need your Windows system installed network adapter TCP/IP protocol, there are two options: (1) make use of the interval between two messages sent by ping. Ping to send multiple messages, in a message to respond, it will wait for a second time to send a message, and the response time for the type system, and network configuration, the IP address is especially crucial, only local loopbac
