Ever needed to send a mail from the command line. It’s pretty simple (provided you already have a mail transfer agent running such as postfix or sendmail).

echo “Type email content here” | mail -s “Your subject” -a attachement-filename.png [email protected]

Let’s say your account name on your PC is ‘user’ and machine name is ‘pc1’. The recipient will find the mail originating from something like [email protected]. Mails replied to the latter won’t be receivable of course. You can therefore specify a reply-to address with the option -r.

echo “Type email content here” | mail -r [email protected] -s “Your subject” [email protected]
