Run the script file after 5 or 10 min after restarting the system
I have created a ruby script file that checks the connection present or not. For example checking port 22 is opened or not.
Firstly I tried with cron job as follows
@reboot find ${HOME}/my_app/check_conn.rb
But it is executing immediately after starting the system.
Now I have to run this script after 5 or 10 min.
How can I do this. Is there any other way for doing this.
Thanks in advance.

A bad hack: Addsleep 600;to the beginning of the command.

I would never execute from cron itself and always create an executable file in /etc/cronjob; Just put anatcommand inside that file to execute it 5 minutes from now?

@dan08 did I have to addsleep 600;before my cron_job or in my script file?

Add sleep 600; to the beginning of your crontab command to make it wait for 600 seconds before proceeding to the next step.
Your new crontab command would look like
@reboot sleep 600; find ${HOME}/my_app/check_conn.rb

Don't do it depending on time, but after establishing a network connection. The right place to do it is below:
/etc/network/if-up.d
