Wait 20 seconds in a batch file

Hello!

I need a little help. I have a batch file that runs at startup on the server and sends a message to the two other PCs on the network to let them know that the server has rebooted (since it doesn't have a screen, it's the only solution we found...).

The problem is that when the client PCs receive the messages, the server’s network services aren’t launched yet. Based on that, if we put a 20-second pause before sending the messages in the batch, would that be enough? And if so, how would you put a 20-second pause in a batch file?

Thanks in advance.

    Stop with your stupid pings:
    1) it's 0% reliable (yeah, the ping on the loopback is around 0 to 16ms, which is 1 clock tick under Windows, and if you don't have a network card, it doesn't work)
    2) it runs a program for no reason (and it uses COM for no reason)

      hi FFS ;)

      I don't agree with you!! because ping also works without a network card like mine ;)

      for 4 seconds: (n-1) ==> the n in this example is equal to 5
      ping -n 5 127.0.0.1
      or
      ping -n 5 localhost

      Re,

      PING /?

      Usage: ping [-t] [-a] [-n echoes] [-l size] [-f] [-i ttl] [-v TypeServ]
      [-r Hops] [-s Hops] [[-j HostsList] | [-k HostsList]]
      [-w Timeout] TargetName

      Options:
      -t Sends the ping request to the specified host until
      interrupted.
      Press Ctrl-Break to display statistics and continue,
      Ctrl-C to stop.
      -a Resolves hostnames from addresses.
      -n echoes Number of echo requests to send.
      -l size Sends the size of the buffer.
      -f Sets the Don't Fragment flag in the packet.
      -i ttl Time to live.
      -v TypeServ Type of service.
      -r Hops Records the route for the number of hops.
      -s Hops Timestamp for the number of hops.
      -j HostsList Loose source route along the host list.
      -k HostsList Strict source route along the host list.
      -w Timeout Timeout for each reply, in milliseconds.

      FFS :

      -w Waiting time for each response, in milliseconds.

      That's it for your point 1: it's reliable.

      Hello,
      Yes ping = poop
      Use the command TIMEOUT /t 30 /NOBREAK
      here in the example, a pause of 30 seconds

    Hi,
    another solution you can use is the SLEEP command..
    you can do a "SLEEP 20" and it will pause for 20 seconds
    I can send it to you if you want because I don't remember where I downloaded or found it!!

    Good night,
    yes choice will work if you write it with the following syntax:

    choice /c:ON /n /t:O,20

    where /n suppresses the display (Y/N) of the letters designated by /C:
    and /t: gives the default result O (Yes) in 20 seconds.

    The command and its switches are valid from DOS versions 6 to 8 (and ?? ...).

      slt

      the choice command does not exist in XP

    Otherwise, a little ping allows you to wait a bit.
    For example: 

    ping -n 5 127.0.0.1

    where '-n 5' is the duration of each ping. If you want to wait 20 seconds, I recommend 
    ping -n 15 127.0.0.1 or... ping -n 20 127.0.0.1

    It's not really the most appropriate command, but it does allow for a pause... The CHOICE command

    http://1100f.free.fr/Batchs/la_commande_choice.htm

    If the user does not respond, a default signal is sent to execute the script. I hope it will be okay.

    Well, I know this topic is a bit old (a lot), but it can be useful for those looking for a solution.

    In Windows 7, there is the timeout command to add a pause.

    timeout /? for more info.
