How do I send email from the linux command line?

Need to email from your linux command line? Assuming the underlying pieces are configured correctly (run the 1st example to see) here are the basics…

Send a test email:
mail -s "Hi there" [email protected]

Include some body text:
echo "This is some body text" | mail -s "Hi there" [email protected]

Email the contents of a file to someone:
mail -s "My Subject" [email protected] < /path/to/your/file.txt
