if you want the job to run once at a future time, instead of cron use at

at 4am tomorrow <<END
command 1
command 2
sleep 600
command 3
command 4
END

One of the advantages of at is that it will execute the commands using your current environment. The limited environment provided by cron is a cause of confusion for many people.

You can create a script.sh like:

#!/bin/bash

command 1
command 2
sleep 600 # 600 seconds = 10 min
command 3
command 4

And then create a cronjob:

0 4 * * * /bin/bash /path/to/script.sh

You can see more info of cron in https://stackoverflow.com/tags/cron/info
