Sending Email from the Terminal

Installing Required Tools

There are several utilities available for sending email via the command line:

• mail
• sendmail
• mutt
• ssmtp
• mailx

We’ll use mailx in this example. To install it on Debian-based systems:

sudo apt update
sudo apt install mailutils

Sending a Simple Email

echo "Hello! This is a test email from the terminal." | mail -s "Test Subject" recipient@example.com

Explanation:

• echo defines the body of the email
• -s sets the subject
• recipient@example.com is the recipient’s address

Sending an Email with an Attachment

echo "Please see the attached file." | mail -s "Attachment Included" -A /path/to/file.pdf recipient@example.com

Reading Email from the Terminal

Using mutt

mutt is a powerful text-based email client that supports IMAP, POP3, and SMTP. To install:

sudo apt install mutt

Basic Configuration Example

Create or edit your ~/.muttrc file:

set imap_user = "your@email.com"
set imap_pass = "yourpassword"
set folder = "imaps://imap.yourmail.com/"
set spoolfile = "+INBOX"

Then launch the client:

mutt

Automating Email with Scripts

Command-line email is perfect for automation. For example, to notify yourself when a backup completes:

mail -s "Backup Completed" your@email.com <<< "The backup finished successfully."

Tips and Best Practices

• Use cron to schedule regular email reports
• Encrypt sensitive messages using GPG
• Test email scripts locally before deploying to production

Conclusion

Managing email from the Linux command line is a practical skill for anyone working in server environments or automation. With tools like mailx and mutt, you can send, read, and automate email tasks without ever opening a GUI. Try it out and see how much more efficient your workflow can become.
