5 Ways to Send Mail from Linux Command Line

When you need to create mail in a shell script, you need to use the command line to send mail knowledge. There are many commands in Linux that can be used to send mail. This tutorial contains five of the most popular command line mail clients, and you can choose one of them. These five commands are:

mail / mailxmuttmpacksendmailssmtp

working principle

Let me explain how the mail command delivers mail to recipients in Linux as a whole. Mail commands compose and send mail to a local mail transfer agent (MTA, e.g. sendmail, Postfix). The mail server communicates with the remote mail server to actually send and receive mail. The process below can be seen in more detail.

1)How to install mail/mailx command on Linux

The mail command is the most common command used by Linux terminals to send mail. mailx is an updated version of the mail command, based on Berkeley Mail 8.1, intended to provide the functionality of the POSIX mailx command and support MIME, IMAP, POP3, SMTP, and S/MIME extensions. Mailx is more powerful in certain interactive features, such as buffering mail messages, spam scoring, and filtering. On Linux distributions, the mail command is a soft link to the mailx command. You can install mail from the official distribution repository by running the following command.

For Debian/Ubuntu systems, install mailutils using APT-GET or APT commands.

$ sudo apt-get install mailutils

For RHEL/CentOS systems, use the YUM command to install mailx.

$ sudo yum install mailx

For Fedora systems, install mailx using the DNF command.

$ sudo dnf install mailx

1a) How to send mail using mail command on Linux

The mail command is easy to use. If you don't need to send an attachment, you can send an email using the following mail command format:

If you want to send an attachment, use the following mail command format:

$ echo "This is the mail body" | mail -a test1.txt -s "Subject" 2daygeek@gmail.com

-a: Used to add attachments to Red Hat-based systems.

-A: Used to add attachments to Debian-based systems.

-s: Specifies the message title.

2)How to install mutt command on Linux

mutt is another popular command to send mail on Linux terminals. mutt is a small but powerful text-based program for reading and sending e-mail on the Unix operating system, and supports color terminals, MIME, OpenPGP, and sorting by mail thread modes. You can install mutt from the official distribution repository by running the following command.

For Debian/Ubuntu systems, install mutt using APT-GET or APT commands.

$ sudo apt-get install mutt

For RHEL/CentOS systems, use the YUM command to install mutt.

$ sudo yum install mutt

For Fedora systems, install mutt using the DNF command.

$ sudo dnf install mutt

2b) How to send mail using mutt command on Linux

Mutt is just as easy to use. If you don't need to send an attachment, you can send the email using the mutt command format below:

$ echo "This is the mail body" | mutt -s "Subject" 2daygeek@gmail.com

If you want to send an attachment, use the mutt command format below:

$ echo "This is the mail body" | mutt -s "Subject" 2daygeek@gmail.com -a test1.txt

3)How to install mpack command on Linux
