1. Install mailx:

The installation of the mailx feature varies from one operating system to another. Below are the commands you need to run for installing mailx features for the most common Linux operating systems i.e. Redhat, Ubuntu, Debian, and CentOS.

2. Send email in Linux using mailx:

Using the mailx command gives you the flexibility to use various flags like email subject, attachment, cc, bcc, etc while sending emails in Linux. Here are the flags that you can use for achieving your requirement.

-semail subject
-aemail attachment
-ccopy email address (cc)
-bblind copy email address (bcc)

The below example sends an email in Linux with an email body, email subject, and an attachment.

$ echo "Email Body" | mailx -s "Email Subject" -a /tmp/log.txt

Send email with multiple attachments:

If you want to add multiple attachments, you can include multiple files in the mailx -a flag to send email in Linux.

$ echo "Email Body" | mailx -s "Email Subject" -a /tmp/log1.txt /tmp/log2.txt

Send email with cc / bcc:

If you want to copy (cc) or blind copy (bcc) some email addresses in your email in Linux, here is an example for you.

$ echo "Email Body" | mailx -s "Email Subject" -a /tmp/log.txt -c -b

The email is sent from the user id that runs the script and from the server where the script is running. If the user id running the mailx command is dbauser and the script is running on a server with the name, then the email is sent from the email id

Read email ids from a text file and send email in Linux:

If you have a scenario where the email ids are present in a file in each line, you can use the below code snippet to read each line from the file and send an email to each line’s content.


while read -r EMAILID; do
    echo "Email Body" | mailx -s "Email Subject" $EMAILID

This example reads one email id in each line from the EMAILCONFIGFILE and sends the email. This continues till an empty line is encountered.

Final words:

That’s all, isn’t it easy? You can tweak the mailx command with different combinations to satisfy your requirement of sending email in Linux using mailx command with attachment or without. I hope this was useful to you.
