There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.
```
mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
```

With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

## Prepare a temporary script that will serve as an editor.

## This script will be passed to ed.
temp_script=$(mktemp)
cat <<'EOF' >>"$temp_script"
1a
Content-Type: text/html
.
$r test.html
w
q
EOF
## Call mailx, and tell it to invoke the editor script
EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
~e
.
EOF
rm -f "$temp_script"

With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.
When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

I had successfully used the following on Arch Linux  where the -a flag is used for attachments  for several years   mailx -s  The Subject    echo -e   nContent-Type  text html  user gmail com  lt  email html   This appended the Content-Type header to the subject header  which worked great until a recent update  Now the new line is filtered out of the -s subject  Presumably  this was done to improve security   Instead of relying on hacking the subject line  I now use a bash subshell          echo -e  Content-Type  text html n      cat mail html      mail -s  The Subject  -t user gmail com   And since we are really only using mailx s subject flag  it seems there is no reason not to switch to sendmail as suggested by  dogbane         echo  To  user gmail com      echo  Subject  The Subject      echo  Content-Type  text html      echo     cat mail html     sendmail -t   The use of bash subshells avoids having to create a temporary file
