How do I use the mail command in linux? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

First, use the help parameter to view all the parameters of mail as follows:

The code is as follows:

Usage: mail [- BDFintv~] [- s subject] [- an attachment] [- c cc-addr] [- b bcc-addr]

[- r from-addr] [- h hops] [- An account] [- R reply-addr] to-addr...

Mail [- BDeHiInNRv~] [- T name] [- An account]-f [name]

Mail [- BDeinNRv~] [- An account] [- u user]

1. Send the title plus text content

Run the command:

The code is as follows:

Mail-s "this is a title" bbmonkey62@163.com

Enter and continue to enter the text, that is, the content of the email

The code is as follows:

This is content

Then press Ctrl+D to exit.

The code is as follows:

EOT

The above is the simplest example. What if we want to send it to multiple mailboxes? Add another email address to the mailbox above, separated by a space, as follows:

The code is as follows:

Mail-s "this is a title" bbmonkey62@163.com admin@163.com

In the above example, the sender is Linux's current login user name, for example, if my current login user name is admin, then the email address sent is admin@163.com, if the mailbox suffix domain name is 163.com. But sometimes we want to write the sender's name, and we don't want to use the default email address, so we can do this:

The code is as follows:

Mail-s "this is a title"-r "myname@zihou.me" bbmonkey62@163.com

At this point, the sender's mailbox becomes myname@zihou.me, and some spam emails use this method to hide their real email addresses.

If we want the recipient to reply to an email with a different email address than our outgoing email address, we can customize the reply email address as follows:

The code is as follows:

Mail-s "this is a title"-r "myname@zihou.me"-R "myreply@zihou.me" bbmonkey62@163.com

Then when the recipient replies, it will be sent to myreply@zihou.me by default, not to the default myname@zihou.me.

2. Send attachments

Sometimes we need to send attachments, then it is very easy, as follows:

The code is as follows:

Mail-s "this is a title"-r "myname@zihou.me"-a "/ home/hadoop/report/3.txt" bbmonkey62@163.com

To be explained here, if our attachment is a small text file, sometimes we do not need to send the attachment. We can directly send the text of the attachment as the content of the email, so it is more convenient to view it through the email, as follows:

The code is as follows:

Mail-s "this is a test" bbmonkey62@163.com < / home/hadoop/project/3.txt

3. There is no need to enter the content of the email to send the email.

In the above example, if you do this, you will find it very inconvenient, that is, each time you enter the content of the email, you need to enter the content after the command runs, and finally press Ctrl+D to complete it. In fact, it doesn't have to be so hard, as follows:

The code is as follows:

Echo "this is content" | mail-s "this is a title" bbmonkey62@163.com

Enter the email content "this is content" through the echo command, which is much easier!

4. Check email

Through the mail command can also check the received mail, this I will briefly say, after all, this is relatively rare, the command is very simple, directly enter mail, there will be received mail, each email corresponds to a serial number, if you want to view an email, directly in? Then enter the digital serial number.

In? Enter help to view all the parameters, as follows:

The code is as follows:

? Help

Separated by spaces. If omitted, mail uses the last message typed.

In? You can also type mail directly to write a letter later, just like the example above, except that there will be a prompt for each step, as follows:

The code is as follows:

? Mail

To: bbmonkey62@163.com

Subject: this is a title
