Subject line with the sendmail command

trilok_pvp — Thu, 08 Oct 2009 14:03:10 GMT

Hi All,

I want to send a mail from command line, I am using sendmail command for the same.

I tried sending mails to myself. I am able to send mails but, i don't know how to specify Subject line.

echo "Disk Report of `hostname` as of `date`" 2> /dev/null > diskreport
df >> diskreport
sendmail " trilok.prasad@gmail.com < diskreport

How can Subject line be specified?

Thanks
Trilok PVP

Hi:

# mailx -s "Disk Report for $(hostname)" myemail@mycompany.com < diskreport

Note the '-s' argument and the use of 'mailx'.

Regards!

Hi (again):

Sendmail isn't intended at a user interface. You can type, line-for-line something like:

sendmail myemail@mycompany.com
Subject: myrepot
This is the body of my message
^D

...Note the line that begins with "Subject:" triggers the subject line. The ^D is a control_D which signifies end-of-file.

Regards!

Shalom Trilok,

Take a look at the script in there. It is a bit more than you need but demonstrates how to control the subject.

You can also use the script to attach a file to an email, delivering your report that way.

Hi Trilok:

OK, this works:

#!/bin/sh
sendmail myemail@mycompany.com <<- EOF!
> Subject: Disk Report from $(hostname)
> $(< /tmp/diskreport)
> EOF!

Again, make sure that the line that begins with "Subject" specifies an uppercase "S" and a colon (:) character as shown.

Regards!

For similar purposes I would use something like this (one line):

/usr/bin/printf "%b" "Subject:subject goes here\nFrom:specify.from@address.com\n" $(cat diskreport) | /usr/sbin/sendmail your@mail.com

The $(cat diskreport) will fill the message body. It is possible to substitute it with plain text or other command if required.

The "Subject:" is a header field in an RFC822 e-mail message; a blank line should separate the body of the message from the headers.

not sure what distro you are using, but if you like mailx you can install it. If this is rhel you can either

up2date -i mailx

or

yum install mailx
