I wrote this script for collecting ping statistic (after I email to a group
the stat file).

1. how can I run this at startup

You can use cron with an entry similar to:

@reboot /path/to/script.sh

This will work as long as your script has the execute bit set for the user trying to run it.

2. how can I restart this script after 3600 counts down

You can use something like sleep, or you can schedule, again using cron, the script to run every 3600 seconds. An entry such as:

0  *   *  *  * /path/to/script.sh

This will re-run your script every hour, on the hour.

3. Is there a program, script or any way more appropriate to track the
packet loss and ping availability.?

I would recommend using some nrpe module you write for nagios and/or cacti to monitor and even graph this information.

Thank you in advance

No problem!
