Linux Script To Send Email

Linux Script To Send Email – In this quick guide we will discuss how to use text output as an email body from the Linux command line. This is great for anyone who wants to run a command and send the output to an email address. Using cron can be an efficient way to get information about your system or a specific application.

First you need a program that can send emails from the Linux command line. I have been using mailx for several years and I recommend it.

Before we get started, you need to make sure your system is set up to send email. If you’re sure it is, you can skip below. If you need to configure your system, then read “How to Mail to ISP SMTP with Postfix”.

To test your system’s mail functionality, simply send an email using our new mailx program.

If your system is configured correctly, you will receive a copy of your host file in your email.

For more information about sending files read “Send a file as an Attachment or Email Body from the Command Line”.

Sending the output of a command is different than sending an email to a preset text file. You can’t just pass it on or you’ll get a vague redirect error.

Now you will be able to execute a script or run a command and send the output to an email address.

It is very easy to run a command and send the output by email. Understanding how a faucet works is important.

Sendmail is a very clear and simple MTA (Mail Transfer Agent) that implements SMTP (Simple Transfer Protocol) and others and can be used to forward emails, usually even on the cheapest KVM VPS running on Linux. Although there is a commercial version available called “Sendmail”, the sendmail we will use in this article is the UNIX-based version, which is compatible with almost all Linux distributions as well as *BSD (FreeBSD), OpenBSD. and variants). Using the send command can be the easiest way to send email in the Linux shell CLI (Command Line Interface), except for mailx, which can be used for mail to easily send and receive letters from the command line. . As the name already suggests, sendmail itself can only send emails and not store received in POP or IMAP mailboxes.

The first interesting piece of information that we may need to test the sending message is the path of the binary file that is executed if we send the message from the command line. To find that out, we will use the command as shown below:

How To Create Documents With Bash Scripts

The above output means that the full path of our command line binary file is /usr/sbin/sendmail, which you need to follow the steps below.

If you want to edit the mail configuration files, you can usually find them in the /etc/mail/ directory on UNIX (FreeBSD, OpenBSD) and Linux (CentOS, Fedora, Debian, Ubuntu). The main sendmail configuration file is /etc/mail/, however configuration is not part of this tutorial. A good place to find more information is the sending manual page, which you can see by running the message manida. Now for the interesting part of the dirmail command line tutorial.

To quickly test if the send command works correctly, so use for example shell scripts, via the command line or even PHP scripts (PHP supports emails to send emails with PHP scripts – you set a path in your php.ini ), you can issue the command below on your UNIX or Linux system:

[email protected] is obviously the email address you want the test email to be sent to. This sendmail command line example will send an empty email with the subject “test send” to [email protected] if the test is successful. You can also send long emails with a subject, body and additional headers if you want, but only to test if the message works, which is usually unnecessary. However, here’s how you can do it:

How To Execute A Command In A Shell Script?

1.) Create a file called mail.txt (or whatever you like) in ~/mail.txt using vim or nano or your favorite text editor.

2.) Paste the following content, but of course correcting the email addresses, because these are examples of sending orders:

That’s it – you can now test sending from the command line and even send full emails with headers in a Linux/UNIX shell. Below is an example of what a simple deployment test might look like on a live system:

One thing I would like to add is that due to the fact that PHP and other scripts can often embed the sending messages, they can also be used to send spam and phishing messages and that is what can happen to shared servers where accounts have been hacked . . by outdated CMS or weak passwords. If you want to know which font or POSIX user is sending spam, you can issue the command below and look at the output:

Although sending can present several risks on shared or insecure systems, it is a small and lightweight MTA that can be used to send email from shell scripts, PHP applications or even directly over the Internet. It also automatically negotiates STARTTLS for encrypted transmission of emails if the remote SMTP server supports it, which is a useful security practice.

More information… Historically, the shell was the native command line interpreter for Unix systems. It has proven to be one of Unix’s greatest features over the years and has grown into a new topic in its own right. Linux offers a variety of powerful shells with powerful functionality, including Bash, Zsh, Tcsh, and Ksh. One of the most amazing features of this shell is its programming. Creating useful Linux shell scripts to handle everyday tasks is a simple matter. Additionally, a decent knowledge of this topic will make you a Linux power user in no time. Stay tuned for a detailed introduction to Unix shell scripting.

Most shell scripts done on Linux involve the bash shell. However, power users who specify options often use other shells such as Zsh and Ksh. We will mostly stick to Linux bash scripts in our examples due to their widespread popularity and huge usage. However, our editors have also tried to explain some examples of shell scripting for non-bash shells. As a result, you will find a large amount of popularity among different shell scripts.

Bash, aka Bourne Again Shell, is the command line interpreter for most Linux distributions these days. It is an update of the old Bourne shell that was first introduced in Version 7 Unix. Learning the shell script will allow you to quickly understand other shell scripts. So, try this simple example yourself to get the first hand experience.

How To Create Bash Scripts Using External Variables And Embedded Scripts

Programmers often learn new languages ​​by learning hello world programming. It’s a simple program that prints the string “Hello World” to standard output. Next, use an editor like vim or nano to create a file and copy the lines below.

The echo command is used to print information in bash. It is similar to the C function ‘printf’ and offers many common options, including escape sequences and redirection.

Run the script to see what it does. The -e option is used to tell echo that the string passed contains special characters and requires extra processing.

Comments are useful for documentation and are a requirement for high-quality code bases. It is common practice to insert comments within codes that deal with important logic. To comment out a line, simply use #(hash) characters in front of it. For example, check out the example bash script below.

Send An Email Using Telnet

This script will generate the number 60. First, check how comments are used with # before a few lines. The first line, however, is an exception. It’s called a shebang and it lets the system know which interpreter to use when running this script.

Many people use multiline comments to document their shell scripts. Check how to do this in the following script called
