How to sleep for five seconds in a batch file/cmd

One hack is to (mis)use the ping command:

ping 127.0.0.1 -n 6 > nul

Explanation:

  • ping is a system utility that sends ping requests. ping is available on all versions of Windows.
  • 127.0.0.1 is the IP address of localhost. This IP address is guaranteed to always resolve, be reachable, and immediately respond to pings.
  • -n 6 specifies that there are to be 6 pings. There is a 1s delay between each ping, so for a 5s delay you need to send 6 pings.
  • > nul suppress the output of ping, by redirecting it to nul.
