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\" >         


        

Answer 1

My version of mail does not have --append and it too smart for the echo -e \n-trick (it simply replaces \n with space). It does, however, have -a:

mail -a "Content-type: text/html" -s "Built notification" address@example.com < /var/www/report.html
