Shell Programming and Scripting

Hi,
I have a application which send mail to the respective client upon success or failure case of file transfer, upon success there is no problem.
But in case of failure that application is running again in cron job,so still success of file transfer the client will get the failure notification. If it happen in weekend there is a big disaster in client mail box

So can it possible to restrict the multiple failure mail send to the client , i mean after 2 failure mail it won't send any notification or such idea be helpful for me.


Thanks

I think something may be wrong in your script. Can you post the part that does email?

Hi Jim,
As the application is just a ELF package, so i can not able to dig it and there may be some case connectivity like session out,traffic or may be server down .
In this case we are using some option to get to know failure case and in script calling the application with that option and using mailx upon failure.

.sh script is in cron say every 30min . So in this case it send 40-50mail for the same failure each time.

What does the crontab look like? I can gues if you'd like, but it won't help you at all.

i believe crontab is working fine for me, but need to restrict the mail upon 1st failure case.
Is there any logic we can implement for this scenario ??

You didn't provide any further documentation of your script (or whatever it is you execute from cron), so can give you only a sketch of a solution. It implies that the (fictitous) program "do_file_transfer" returns 0 (success) or 1 (failure) and there is a (fictitous) program "mail_to_customer", which handles the mail:

Code:

#!/bin/ksh

typeset chAddress=""
typeset fErrlog="/your/list/with/addresses.errors"
cat /your/list/with/addresses | while read chAddress ; do
     if [ $(grep -c "$chAddress" "$fErrlog") -le 2 ] ; then
          do_file_transfer $chAddress
          if [ $? -gt 0 ] ; then
               print - "$chAddress" >> "$fErrlog"
               mail_to_customer "$chAddress" "Sorry, your file transfer failed."
          fi
     fi
done

exit 0

I hope this helps.
