macOS Piping help

[albacor]

In Terminal, I'm trying to replace SUBJECT and BODY from the command below:

printf "From: Sender Name <sender@domain.com>\nTo: recipient@domain.com\nSubject: [COLOR="SeaGreen"][B]SUBJECT[/B][/COLOR]\n\n[COLOR="Red"][B]BODY[/B][/COLOR]\n" | /usr/sbin/sendmail -F "Sender Name" -f "sender@domain.com" "recipient@domain.com"

with the piping of

ls *

I just can't figure out how to do it, any kind soul to help me with this please?

printf "From: Sender Name <sender@domain.com>\nTo: recipient@domain.com\nSubject: $(ls *)" | /usr/sbin/sendmail -F "Sender Name" -f "sender@domain.com" "recipient@domain.com"

Note that file names containing % in the `ls` may be interpreted as format specification by the printf

printf " "From: Sender Name <sender@domain.com>\nTo: recipient@domain.com\nSubject: $(ls *)" | /usr/sbin/sendmail -F "Sender Name" -f "sender@domain.com" "recipient@domain.com"

Damn, why was it so simple? I feel like a fool

Thanks a lot pal
