emailing files from the command line
From Sharkysoft Wiki
Sometimes you just want a quick and easy way to email someone a file from the command line. Here's one method that works quite well:
mime-construct --file-attach <file name> --to <email address> --subject <subject text> --string <message body>
If your system does not support the mime-construct command, it is probably because you don't have the mime-construct package installed. You can install this package by typing:
sudo apt-get install mime-construct
