Send email from shell

Thanks a lot it works fine!

I had tried the mail command, but with echo and not printf.

Thanks again!

The following will work in both FreeNAS 0.7 and FreeNAS 8.0.1:

Code:

#!/bin/bash

FROM=me@mydomain.com
TO=me@mydomain.com
SUBJECT="`hostname`: Test Email"
BODY=""

PRINTF=/usr/bin/printf
MSMTP=/usr/local/bin/msmtp
MSMTPCONF=/var/etc/msmtp.conf
#...
BODY="Something"
#...
# Send email in FreeNAS 0.7.x
[   -f $MSMTP ] && $PRINTF "From:$FROM\nTo:$TO\nSubject:$SUBJECT\n\n$BODY" | $MSMTP --file=$MSMTPCONF -t
# Send email in FreeNAS 8.0.1+
[ ! -f $MSMTP ] && $PRINTF "$BODY" | mail -s "$SUBJECT" $TO

Thanks for sharing... Does it work also for FreeNAS 8.0.2?

Yes.

Just for clarification.
Since 8.0.2 we do not ship msmtp as part of the installation anymore. Hence the check for msmtp.
From now one should just "mail" for that matter.

Pretty sure msmtp wasn't there in 8.0.1 either, and maybe not versions prior to that.

If you are interested in supporting only FreeNAS 8.x then sure, just use mail, but if you are supporting a mixed environment (FreeNAS 0.7.x and 8.0.x) then the example script is what you need to support both platforms with a common code base.
