pipe curl output to email

Question

I want to pipe output from the curl command to the email however I receive an empty attachment file when I run this script:

#!/bin/bash

STATUS=$(curl -I example.com)

echo $STATUS | mail -s "Test" [email protected]

I've also tried to group into a block but this also didn't work:

#!/bin/bash    
{
curl -I example.com
} | mail -s "Test" [email protected]

OS: Red Hat 6.3

# mail -V
12.4 7/29/08

Curriously, your commands seem correct (both). What version of mail are you using, try this in a freed environnement. — F. Hauri - Give Up GitHub

Assuming your mail binary is this one, try adding the option -a -.

Edited:

Try simply

curl -SIo /dev/stdout example.com 2>/dev/null | mail -s "Test" [email protected]

Well, if it's a mail problem. Your description seem strange, which version of mail are you using?

or maybe asking for sendmail directly:

/usr/sbin/sendmail [email protected] < <(
    echo $'From: [email protected]\nTo: [email protected]\nDate: '$(
        env LANG=C date +%c)$'\nSubject: Test'
    echo
    curl -SIo /dev/stdout 2>/dev/null example.com)

You could even build some more sophisticated job:

MyVar="$(curl -SIo /dev/stdout 2>/dev/null example.com)"
/usr/sbin/sendmail [email protected] < <(
    echo $'From: [email protected]\nTo: [email protected]\nDate: '$(
        env LANG=C date +%c)$'\nSubject: Server resp: '${MyVar%%$'\r'*}
    echo
    echo "$MyVar")

So you could have the initial server response in the subject.

This is not a reserved sendmail feature!

I was using this kind of method from many years, first under sendmail, but this work with the same syntax (ie calling ../sbin/sendmail binary or wrapper directly, with a formated mail as header + empty line + body ) with all MTA I've ever used upto now (sendmail, qmail, postfix, exim).

Nota Some (old) MTA complain about presence (or not) of a CR or \r at end of lines, maybe some sed 's/$/\r/' could help.

Hi, this also attached an empty file. I would like to pipe this into message body.

Did you need only the header or the output of curl (transfer stats) too?

This also creates an attachment. Basically I just monitor a website and if it's down I would like to know the header output from curl but it looks like it's not easy to pipe it into message body and I'm not sure why.

Yes, curl -SIo /dev/stdout 2>/dev/null www.test.com | mail -s test myself work fine, but I'm Debian user, on squeeze, with bash 4.1.5(1)-release and mail is coming with my version of Exim (not postfix). At all, I know this work under postfix too!

@HTF I'v tried now, under postfix exactly the same syntax as my last sample whith MyVar... and using sendmail sbin command. This work perfectly : I've recieved a mail with subject: Server resp: HTTP/1.1 200 OK (postfix version 2.7.1-1+squeeze1)
