How do I schedule a timed reboot of my server in seconds?

linux bash shell reboot

I’m using bash shell on Linux …

$ uname -a
Linux sandbox.mydomain.com 3.4.76-65.111.amzn1.x86_64 #1 SMP Tue Jan 14 21:06:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

although it would be nice if I could come up with a solution in any bash supported environment. My question is, in my script I want to scheduled a delayed reboot of my server in 5 seconds. So far, I have the below, but it takes 60 seconds …

# Timed reboot of server
sudo shutdown -r 1

# Fail if any of the sub-deployments failed.
if [[ ( $PROC1_STATUS -ne 0 ) ||
      ( $PROC2_STATUS -ne 0 ) ||
      ( $PROC3_STATUS -ne 0 ) ]]
then
        exit 1;
fi

Does anyone know how I can adjust the above except make the timed reboot in 5 seconds instead of a minute? The solution doesn't have to use "shutdown" but it was the only tool I could find.
