Sending e-mail from a script

arobinson888 · September 2, 2015

Hello,

I am trying to get rsync to copy files to an external hard drive, log everything to a file, and then e-mail me that file after the operation has complete. So far rsync copy and writing to log file work fine, but I can not get the script to e-mail me the log file. I have set up the SMTP settings in unraid 6.1 notifications, and the test function does send an e-mail properly. Below is the script I am running/ working on.

#!/bin/bash

#File and directory backup script
# Andrew Robinson 2015

#Each line is set up to run rsync on a specific directory and back up to external HDD.  
#after sync completed, log file with results is writen
#then e-mailed off to me

echo "Backing up data directories to removeable hard drive"
rsync -avh --delete /mnt/user/ /mnt/disks/ST4000DM000_1F2168_Z300HVNP/ --log-file=/var/log/backup_rsync.log
echo "Backup complete"
cat /var/log/backup_rsync.log | mail -s "backup_rsync.log" [email protected]

Thanks

I use a line similar to this

/usr/local/emhttp/webGui/scripts/notify -i normal -s "Cache Drive Backup Completed" -d " Cache Drive Backup completed at `date`"

to get notifications from my scripts.

If you want to mail with the mail command then mailx slackware package needs to be installed.

This isn't done by default because LT wants people to use the notification system.

If this script runs in cron, stdout and stderr normally get mailed to whatever you've configured in the mail settings page.

Within the script you can do a cat of the log file and will get mailed with the job's output.

I.E. you should not need the cat logfile | mail -s 'subject'

You can cat the logfile within the script and it will be included with job output via cron.

To send it as a separate log, you'll need to install mailx or call SSMTP directly.

http://linux.die.net/man/8/ssmtp

Here's a quick example of how to do it via ssmtp directly. Note I have the -v verbose switch on, normally that would not be included.

root@unRAIDb:/tmp# ls -l > logfile

root@unRAIDb:/tmp# cat example_ssmtp.sh

#!/bin/bash

cat - logfile <<-EOF | ssmtp -v [email protected]

Subject: logfile for `date`

EOF

root@unRAIDb:/tmp# ./example_ssmtp.sh

I've update my script and it now seems to be working, but I'm getting the error message

ssmtp: 550 5.7.60 SMTP; Client does not have permissions to send as this sender

I'm not sure how to fix this error. The sending e-mail address in my smtp settings (notifications) is the same e-mail address I have set up in this script.

It is recommended to use the notify command to send notifications (including email), and not use another mail or smtp application.

root@unRAIDb:/tmp# /usr/local/emhttp/webGui/scripts/notify

notify [-e "event"] [-s "subject"] [-d "description"] [-i "normal|warning|alert"] [-m "message"] [-x] [-t] [add]

create a notification

use -e to specify the event

use -s to specify a subject

use -d to specify a short description

use -i to specify the severity

use -m to specify a message (long description)

use -x to create a single notification ticket

use -t to force send email only (for testing)

all options are optional

notify init

Initialize the notification subsystem.

notify smtp-init

Initialize sendmail configuration (ssmtp in our case).

notify get

Output a json-encoded list of all the unread notifications.

notify archive file

Move file from 'unread' state to 'archive' state.

notify does not look like it's capable of accepting stdin and sending that data.

i.e. as in sending the log with a subject.

for the ssmtp error,

Looks like the smtp server requires more then mine did.

Try adding a From: as it normally defaults to the root user.

#!/bin/bash

ls -l > logfile

cat - logfile <<-EOF | ssmtp -v [email protected]

From: [email protected]

Subject: logfile for `date`

EOF
