I need to send email with html format. I have only linux command line and command "mail".

Currently have used:

echo "To: address@example.com" > /var/www/report.csv
echo "Subject: Subject" >> /var/www/report.csv
echo "Content-Type: text/html; charset=\"us-ascii\"" >> /var/www/report.csv

echo "<html>" >> /var/www/report.csv
mysql -u ***** -p***** -H -e "select * from users LIMIT 20" dev >> /var/www/report.csv
echo "</html>" >> /var/www/report.csv

mail -s "Built notification" address@example.com < /var/www/report.csv

But in my mail-agent i get only plain/text.

alt text

On OS X (10.9.4), cat works, and is easier if your email is already in a file: 

cat email_template.html  | mail -s "$(echo -e "Test\nContent-Type: text/html")" karl@marx.com

With heirloom-mailx you can change sendmail program to your hook script, replace headers there and then use sendmail.

The script I use (~/bin/sendmail-hook):

#!/bin/bash

sed '1,/^$/{
s,^\(Content-Type: \).*$,\1text/html; charset=utf-8,g
s,^\(Content-Transfer-Encoding: \).*$,\18bit,g
}' | sendmail $@

This script changes the values in the mail header as follows:

  • Content-Type: to text/html; charset=utf-8
  • Content-Transfer-Encoding: to 8bit (not sure if this is really needed).

To send HTML email:

mail -Ssendmail='~/bin/sendmail-hook' \
    -s "Built notification" address@example.com < /var/www/report.csv

Make a file called tmp.html and put the following line in it:

<b>my bold message</b>

Then paste all this into the commandline: (with the parenthesis and all).

(
  echo To: youremail@blah.com
  echo From: el@defiant.com
  echo "Content-Type: text/html; "
  echo Subject: a logfile
  echo
  cat tmp.html
) | sendmail -t

The mail will be dispatched. And the message appeared as bold instead of with the <b> tags.

Very old question, however it ranked high when I googled a question about this.

Find the answer here:

Sending HTML mail using a shell script

I found a really easy solution: add to the mail command the modifier -aContent-Type:text/html.

In your case would be:

mail -aContent-Type:text/html -s "Built notification" address@example.com < /var/www/report.csv

I was struggling with similar problem (with mail) in one of my git's post_receive hooks and finally I found out, that sendmail actually works better for that kind of things, especially if you know a bit of how e-mails are constructed (and it seems like you know). I know this answer comes very late, but maybe it will be of some use to others too. I made use of heredoc operator and use of the feature, that it expands variables, so it can also run inlined scripts. Just check this out (bash script):

#!/bin/bash
recipients=(
    'john@example.com'
    'marry@not-so-an.example.com'
#   'naah@not.this.one'
);
sender='highly-automated-reporter@example.com';
subject='Oh, who really cares, seriously...';
sendmail -t <<-MAIL
    From: ${sender}
    `for r in "${recipients[@]}"; do echo "To: ${r}"; done;`
    Subject: ${subject}
    Content-Type: text/html; charset=UTF-8

    <html><head><meta charset="UTF-8"/></head>
    <body><p>Ladies and gents, here comes the report!</p>
    <pre>`mysql -u ***** -p***** -H -e "SELECT * FROM users LIMIT 20"`</pre>
    </body></html>
MAIL

Note of backticks in the MAIL part to generate some output and remember, that <<- operator strips only tabs (not spaces) from the beginning of lines, so in that case copy-paste will not work (you need to replace indentation with proper tabs). Or use << operator and make no indentation at all. Hope this will help someone. Of course you can use backticks outside o MAIL part and save the output into some variable, that you can later use in the MAIL part — matter of taste and readability. And I know, #!/bin/bash does not always work on every system.
