cron sending multiple emails

prophoto · 10-04-2013, 01:52 PM

Hi Everyone I have a cron job setup to run a script which uploads daily backups to Amazon S3 via s3cmd. For some reason I receive about 75 emails while this script is running. Here is the script, any idea why it sends all of these emails?

#!/bin/bash

DIRECTORY="/var/www/backups/"

echo uploading to S3 with reduced redundancy...
/root/s3cmd/s3cmd put --recursive --rr $DIRECTORY/*.zip s3://backups/
echo Done uploading to s3, deleting files...
rm -rf $DIRECTORY/*.zip
echo Finished!

Code:

#!/bin/bash
DIRECTORY="/var/www/backups/"  

echo uploading to S3 with reduced redundancy...
/root/s3cmd/s3cmd put --recursive --rr $DIRECTORY/*.zip s3://backups/
echo Done uploading to s3, deleting files...
rm -rf $DIRECTORY/*.zip
echo Finished!

You don't tell us what the emails say, or how many files you're putting to S3, but according to the s3cmd instructions, it will echo something out for each file it pushes up. So...75 files, 75 echo statements. But, without seeing what any of the emails say, or knowing anything about your environment, we can't speculate much.

Here's an email...the number of files varies.

uploading to S3 with reduced redundancy...
Done uploading to s3, deleting files...
Finished!

Apparently it is sending an email for each loop, any idea how to stop that?

Loop?? The bash script you posted doesn't have a loop in it. Did you post the ENTIRE script, or just part of it? Or is that script called from another script somewhere?

cron will send an email when its jobs 'see' stderr or stdout
remove the echos, and you will get no emails

However, I do not see why you are getting ~75 emails, that script should only send one
How often does that cron run?
Show us your crontab entry
