Interaction between Linux staff

There is no QQ or MSN in the command line. What if you want to communicate with other online personnel?

1. First, check who is online.
WHO: You can view which users are online and when they log on;
W: its function is similar to that of WHO, but it can display more detailed information (including what other users are currently doing, wow, watching QQ live)
There are also last and lastlog to show which users have logged on and their logon logs recently.

2. After finding the online user, let's talk about it!

// Communicate with other users
# Write dduyoung
Why didn't I bring me breakfast this morning? Do you want to mail your account.
// After the message is input, CTRL + D is complete and the message will be sent out.

// What if I want to "group? Neither.
# Wall "good morning! "

// Write all to understand this command. The usage of write is the same, but you don't need to connect a single user name, because you are a group

3. Do Not Disturb
Messages sent by others will interrupt your work. If you are suddenly disturbed by other people's messages in man write, it will be uncomfortable (especially when the boss is standing behind you, your friend sent you a video request, followed by a mm image ......).

// Do Not Disturb settings, which is quite simple
# Mesg n
// "No message" indicates that you do not want to receive any message.

// Now I am busy. I am suddenly looking for someone to ridicule Dashan.
# Mesg y

4. You have to say it again. QQ can leave a message. Which of the following statements about Linux. Mail is used below

# Mail dduyoung-s "don't pay back! "
I always don't pay back, and never think I gave it to you again!
.
Cc:

// After the message is written, You need to press enter and enter ". ", Press enter, and the system will display" cc: ". If you want to copy the message to other people, write their account in it. If you don't need it, press enter and the email will be sent.

// In the mail Editor, it is inconvenient, and it is not as easy as vim. Then you can write the letter to a text file (mymesg) first, and then:
# Mail dduyoung-s "do not pay back" <mymesg

How can I receive emails? Simply press the MAIL command in the command line.
# Mail
When you check the email address in mail, you will have your own command prompt (&) and the following available commands are available:
? Show Help Information
Z is similar to the next page.
N view an email, N10, and 10 emails (use numbers directly)
D delete mail, D10, or delete a series of mail d10-100
Save s. Append the email content to a file. S 10/home/dduyoung/mymail
X. Exit the mailbox and cancel all operations in the mailbox. (Even if you delete the email, it is useless because you have canceled the operation)
Q: exit the mailbox and use all the operations that have just taken effect.
The above are several basic commands. Check other commands by yourself. Anyway ...... It is more complicated than QQ messages.
