How to send email from Terminal?

I know there are ways to send email from terminal in Linux/MacOS, but I can't seem to find proper documentation on how to do that.

Basically I need it for my bash script that notifies me every time there is a change in a file.

Solution 1:

echo "this is the body" | mail -s "this is the subject" "to@address"

Solution 2:

Go into Terminal and type man mail for help.

You will need to set SMTP up:

Eg:

mail -s "hello" "[email protected]" <<EOF
hello
world
EOF

This will send an email to [email protected] with the subject hello and the message

Hello

World
