Sleeping in a batch file

When writing a batch file to automate something on a Windows box, I've needed to pause its execution for several seconds (usually in a test/wait loop, waiting for a process to start). At the time, the best solution I could find uses ping (I kid you not) to achieve the desired effect. I've found a better write-up of ithere, which describes a callable "wait.bat", implemented as follows:

@ping 127.0.0.1 -n 2 -w 1000 > nul@ping 127.0.0.1 -n %1% -w 1000> nul

You can then include calls to wait.bat in your own batch file, passing in the number of seconds to sleep.

Apparently the Windows 2003 Resource Kit provides a Unix-like sleep command (at last!). In the meantime, for those of us still using Windows XP, Windows 2000 or (sadly)Windows NT, is there a better way?

I modified thesleep.py script in theaccepted answer, so that it defaults to one second if no arguments are passed on the command line:

import time, systime.sleep(float(sys.argv[1]) if len(sys.argv) > 1 else 1)

It pings itself repeatedly, waiting a second between each ping, and then it returns to the calling program, i don't see the infinite loop, but i have tested it myself.

My mistake, there's no infinite loop. However, as mentioned in one of theother answers, it's better toping something not just once, and use the-w Timeout option for the delay-time in milliseconds rather than the-n Count whole number-of-retries option.

-w Timeout may be better, but i made sure it pings one more time than the time entered.
