How send email from command line specifying the email subject and using postfix?

Question

I installed Postfix, and get the /usr/lib/sendmail binary. What I want is send an email alo

/usr/bin/printf "%b" "EMAIL_BODY" | /usr/lib/sendmail -s "EMAIL_SUBJECT" [email protected]

But the -s option is not recognized. How send email from command line specifying the email subject and using postfix?

Solution

Take a look at mailx:

echo "hello world" | mailx -s "Test from CLI" [email protected]
