shell script help

hi all
i have a requirement to get alert mails in my mail box on every 1st and second saturday at a specific time say 5.30EST.how can i write a script such that i will get mail alerts on those 2 weeks every month

What alerts are these? Will these be sent out if anything on the system is out of the ordinary? Or are you just looking to send mails at a specific date/time?

In either case, use cron. Check the crontab man page for details of how to set it up. If you are looking to actually monitor anything on a system, then you will have to write the script to handle that.

yes this will only send mails...
