How to send email from the Linux command line

The Linux command line can be very powerful once you know how to use it. You can parse data, monitor processes, automate backups and do a lot of other useful and cool things using it. There often comes a need to generate a report and mail it out. It could be as simple a requirement as a notification that the day’s backup went through fine, or did not. I’ll help you get started with sending mails from the Linux command line and in shell scripts. We will also cover sending attachments from the command line. We will begin with the “mail” command.


First run a quick test to make sure the “sendmail” application is installed and working correctly. Execute the following command, replacing “” with your e-mail address.

# mail -s “Hello world”

Hit the return key and you will come to a new line. Enter the text “This is a test from my server”. Follow up the text by hitting the return key again. Then hit the key combination of Control+D to continue. The command prompt will ask you if you want to mark a copy of the mail to any other address, hit Control+D again. Check your mailbox. This command will send out a mail to the email id mentioned with the subject, “Hello world”.

To add content to the body of the mail while running the command you can use the following options. If you want to add text on your own:

# echo “This will go into the body of the mail.” | mail -s “Hello world”

And if you want mail to read the content from a file:

# mail -s “Hello world” < /home/calvin/application.log

Some other useful options in the mail command are:

-s subject (The subject of the mail)
-c email-address (Mark a copy to this “email-address”, or CC)
-b email-address (Mark a blind carbon copy to this “email-address”, or BCC)

Here’s how you might use these options:

# echo “Welcome to the world of Calvin n Hobbes” | mail -s “Hello world” -c -b


One of major drawbacks of using the mail command is that it does not support the sending of attachments. mutt, on the other hand, does support it. I’ve found this feature particularly useful for scripts that generate non-textual reports or backups which are relatively small in size which I’d like to backup elsewhere. Of course, mutt allows you to do a lot more than just send attachments. It is a much more complete command line mail client than the “mail” command. Right now we’ll just explore the basic stuff we might need often. Here’s how you would attach a file to a mail:

# echo “Sending an attachment.” | mutt -a -s “attachment”

This command will send a mail to with the subject (-s) “attachment”, the body text “Sending an attachment.”, containing the attachment (-a) Like with the mail command you can use the “-c” option to mark a copy to another mail id.


Now, with the basics covered you can send mails from your shell scripts. Here’s a simple shell script that gives you a reading of the usage of space on your partitions and mails the data to you.

df -h | mail -s “disk space report”

Save these lines in a file on your Linux server and run it. You should receive a mail containing the results of the command. If, however, you need to send more data than just this you will need to write the data to a text file and enter it into the mail body while composing the mail. Here’s and example of a shell script that gets the disk usage as well as the memory usage, writes the data into a temporary file, and then enters it all into the body of the mail being sent out:

df -h > /tmp/mail_report.log
free -m >> /tmp/mail_report.log
mail -s “disk and RAM report” < /tmp/mail_report.log

Now here’s a more complicated problem. You have to take a backup of a few files and mail then out. First the directory to be mailed out is archived. Then it is sent as an email attachment using mutt. Here’s a script to do just that:

tar -zcf /tmp/backup.tar.gz /home/calvin/files
echo | mutt -a /tmp/backup.tar.gz -s “daily backup of data”

The echo at the start of the last line adds a blank into the body of the mail being set out.

This should get you started with sending mails form the Linux command line and from shell scripts. Read up the “man page” for both mail and mutt for more options (enter the commands “man mail” and “man mutt” for the full manual on each).

    using mail
    mail -s “My Subjet” < /home/tmp/body.txt

    sometimes I get an email and sometimes I don't. Sometimes they appear fast in the inbox, sometimes it takes minutes/hours. Usually, the first email sent (of the day) goes fast, the others, who knows??

    cant the "mail" service be restarted? or anyone have an idea as to why/how this happens???

    1. you’d need to wrap it in a if statement, I doubt this could be done just with mail. Something like:
      if [ `du /path/to/log.log` -gt 0 ]
      mail -s “file de log” < /path/to/log.log

  15. According to other websites you can send attachments using “mail” if you pipe the attachment through uuencode into the mail command line. Examples:

    uuencode surfing.jpeg surfing.jpeg | mail
    (cat mailtext; uuencode surfing.jpeg surfing.jpeg) | mail

  18. I have a problem: I can’t visualise the mail content in webmail or thunderbird when I send a mail with a script from a cron schedule:
    mail -s “avisobckmensual”

    I receive the mail but instead of having content, I receive an empty mail with an attachment named “subjet”.octet-stream

    BUT, if I run the script directly from the terminal… it works flawlessly.

    Can you help me?

  27. All of you that had to install sendmail (or postfix, or any of the other bloated MTAs), if all you want is to get emails out of a machine and on to a mail smart host, take a look at ssmtp (it’s in APT with that name if you are a Debian/Ubuntu user). It’s one and only function is to “forward” the mails it receives to a mail smart host.

  30. Hey There

    Been working on this all day (im a big linux noob) and finally got a solution that lets me set the “from” part, with line breaks, all piped into one line. Im going to use this with the exec command from within php to spawn off emails but not loose application speed (hopefully)

    printf “This is the main body of the mail\n with line break” | mail -s “Subject of the Email” -f

    hope this help someone else

  31. You can simply do:
    echo -e “Hello\nWorld” | mail your@email

    However, not all systems support -e option on echo so it’s more portable to use:
    printf “Hello\nWorld” | mail your@email

  35. martin: have a look at – it is designed to run from a script or a cron job and send email through a specified server. For example: --server --from --to some@body.else --subject Blah --attach /path/to/a/picture.png

    It can also authenticate with a Gmail username and password among other things.

  36. Basically have a test script, whose output comes by mail to me with the use of the command taken from this article:

    echo `my test script` | mail -s “Test Result”

    the problem here is that when i do this.. it works correctly on the mailing front, however the mail that i then get ignores the line breaks in the output of the scripts. I really need the line breaks for readability of the output results..

    any pointers on how i could achieve this ?? .. would really like some help here

  37. Hi

    You can actually send binary attachment via “mail” the following way :

    uuencode /etc/hosts /etc/hosts | mail -s “mail with binary attachment”
