How to send emails from the command line in Linux

Use the mail command... Specify the sender with the -r switch ------------------------------------- ``` mail -s "Yer subject" [email protected] -- -r "[email protected]" ``` Use echo to send your emails ---------------------------- ``` echo -e "TEST\n.\n" | mail -s "subject" [email protected] -- -r "[email protected]" ``` Note that we use the -e switch to preserve new lines. Use a file as the contents of your email ---------------------------------------- ``` mail -s "subject" [email protected] -- -r "[email protected]" < /tmp/email ```
