How to send HTML email using linux command line

Question

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\" >

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
