Install automatically email notification after finished a script in Linux

In this example we will work with gmail account. We must go click the gear icon in gmail page, go to Settings, go to the tab Forwarding POP/IMAP, and click the Configuration instructions link in IMAP Access row.

Then click Enable IMAP.  Note the mail server information and use that information for further settings as shown in the next section.

Before proceeding further visit https://www.google.com/settings/security/lesssecureapps and check Turn on radio button.

Install mutt

Ubuntu

sudo aptitude install mutt

sudo apt-get install mutt

Configure Mutt

We need create:

mkdir -p ~/.mutt/cache/headers
mkdir ~/.mutt/cache/bodies
touch ~/.mutt/certificates

A mutt configuration file  called muttrc

touch ~/.mutt/muttrc

We modify mutter file:

vim ~/.mutt/muttrc

Add following configurations

set ssl_starttls=yes
set ssl_force_tls=yes
set from = "user@gmail.com"
set realname = "Your name"
set imap_user = "user@gmail.com"
set imap_pass = "password"
set folder = imaps://imap.gmail.com/
set spoolfile = "+INBOX"
set postponed ="+[Gmail]/Drafts"
set header_cache =~/.mutt/cache/headers
set message_cachedir =~/.mutt/cache/bodies
set certificate_file =~/.mutt/certificates
set smtp_url = "smtp://user@smtp.gmail.com:587/"
set smtp_pass = "password"
set move = no 
set imap_keepalive = 900

Send a email

Now  is ready to start sending emails.

mutt -s "Subject" user@icloud.com < message.txt

And if you want to send an attachment

mutt -s "Subject" user@icloud.com < message.txt -a /tmp/photo.jpg

-s => is the subject

-a => is the attachment 

message.txt  => is the message itself

This is another way to write the test, having the body in the same line.

echo "body" | mutt -s "Subject" user@icloud.com -a /tmp/photo.png

And you can add those command in any file or script.
