Quick tutorial for sending an email in bash.

To work, your system must have the following : postfix or sendmail, mailx package (and dependencies).

Define the variables :
# script to send simple email
# email subject
# Email To ?
# Email text/message

Start the message :
echo "This is an email message test">$EMAILMESSAGE
echo "This is a second line">>$EMAILMESSAGE
echo "This is a third line">>$EMAILMESSAGE

Send the email :
# send an email using /bin/mail
/bin/mail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE

In this script, you can add all the variables you want (ie : df, free, uptime, hostname, date…) ;)
