Need minimum send an email from shell script command

the server does have perl due to some mysql monitoring scripts.  I know php and bash scripting but im not too familiar with perl but i do know how to install perl modules...

How would you go about sending an email using "Email::Send::SMTP" ?  Do you have any examples?

Here's a script that uses Mail::Sender rather (it has no dependencies on other modules).
It works by taking standard input as the mail message that you want to send, and assumes that you can set the sender, recipient and subject in advance.

So you would use it something like this (assuming you call the script mailer.pl):

echo "Hello There" | ./mailer.pl

#!/usr/bin/perl
 
use Mail::Sender;
 
$smtphost = '192.168.29.80';
$from     = 'sender@somedomain.com';
$to       = 'recipient@somedomain.com';
$subject  = "Some Subject";
 
$msg = "";
while (<>) {
  $msg .= $_;
}
 
$mailer = new Mail::Sender {
            smtp => $smtphost,
            from => $from,
            to   => $to
          };
 
$mailer->MailMsg({
                 to => $to, 
                 subject => $subject,
                 msg=> $msg
                });

Incidentally, this perl module is also good for sending messages with file attachments in case that is your need.

I'm sure you server as the "mail" command on it. Use that for sending out email:

# cat /path/to/body/of/email | /bin/mail -s "subject here" recipient@somedomain.com

This will cause the contents of the /path/to/body/of/email file to be emailed out. You can also use "echo" instead:

# echo "this string will be in the body of the email" | /bin/mail -s "subject here" recipient@somedomain.com

It's a piece of cake to script in bash to:

#!/bin/sh
SUB="subject here"
TO="you@yourdomain.com"
BODY="Body here"
 
echo $BODY | /bin/mail -s $SUB $TO

after setting up some other servers as well, I realized our "web" servers will need to send out email via php so i guess my question goes back to the original question now as i dont want to use perl....

What can i do to install a small bin file or small service that does nothing more than send out a real simple email by typing the generic/common "mail" command ?? I dont need to receive mail at all only send (mostly for just notifications and/or alerts.  Can I just do an "apt-get MAILSERVICE" ? I want something slim that sends only. I dont need any listening service.

PHP has function for natively sending mail through the mail() function. You set the SMTP server to use in php.ini. If you need to have PHP on your server, you might as well also load the php-cli package which then allows you to call the PHP mail function from a script too.

So, from a shell file:

#!/bin/bash

php myphpcodefilethatmailsstuff.php

You can install php-cli with apt-get install php-cli

maybe im not being clear...

There is no /bin/mail on the server or in any of the other /bin/ directories.

My question is... using something like you mention "apt-get install"... What can I install that is simple and low in resources that would give me a /bin/mail or similar.

All I need to be able to do is send out. I dont need to receive nor do I need any services installed that will be listening for anything.
