Logic to send email alerts only 5 times a day

Shell Programming and Scripting
1

Hi,

I have written below disk space monitoring script to monitor disk space every minute. I have scheduled this script through cron. But now my problem is this script alerts the users continuously until the space is freed up. These emails are filling up the inbox exponentially until the space has been freed up. Please let me know how to stop sending the email alerts after 5 times and check for next day if the space is not freed up, then repeat the process.

Is your alertlist a single person?
If so, after you email, do the following
append a file with some key info
date (as YYYYMMDD), alertlist

Then, before you email, you could do a

cat logfile | grep YYYYMMDD | grep alertlist | wc -l

and see if you have already sent five times

My alert list has multiple recipients. Please let me know how to do it.

If alertlist has many names, then follow same idea, just break the line into individual names. Write each entry to the log file.
You will also need to break you email into individual emails in order to check for existence of five prior messages for the same day.

hard for me to say how to break apart your alertlist, since I do not see where you build that variable inside your script.
