The syntax of this command is:

NET SEND {alias | /DOMAIN[:name] | \* | /USERS} message

    (Note that text must be provided on the command line.  NET SEND cannot
    take message text from standard input.)

This command sends messages to other computers or users on the network.

COMMENTS

A UNIX system server can send messages, but it cannot
receive them.

You cannot send messages to Macintosh client users.

To send a short message to someone else on the local area
network, type the "net send" command as follows:

    net send alias message

The text of your message may also be contained within
quotation marks.

If the message you want to send is longer than one line,
type the "net send" command followed by an alias and press
"return".

Clients have different limits on the size of
messages they can receive. When the Messenger service is
using expanded memory, the default size of messages is
16,384 bytes. If the Messenger service is not using expanded
memory, the default and recommended maximum size of messages
is 128 bytes.

If you use the \* option to send a broadcast message, the
message is limited to 128 characters.  If you try to send a
longer broadcast message, extra characters are lost and the
receiver is not notified that the message is incomplete.

To send a message to another user, the recipient's client
must be running the Messenger service.  When your message is
successfully received, the server displays the following
message: Message successfully sent to .
If you use an alias that the server does not recognize, or if
the Messenger service is not running on the recipient's
computer, an error message appears.

You can broadcast messages to all aliases in your local
domain (use \* or /DOMAIN) or a different domain (/DOMAIN:name).
Broadcast messages must be 128 characters or fewer.
Use this feature with discretion.

If you wish to send a message to another computer, both
computers must be running the same protocol stack.  For
example, if you send the broadcast message "net send \*", the
message is sent to the network represented by LANAO.

EXAMPLES

To send the message Meeting changed to 3 p.m. Same place.  
to the alias jackst, type the following:

    net send jackst Meeting changed to 3 p.m. Same place.

To inform every user on the domain that a party is being
held in the cafeteria, type the following:

    net send \* Party in the cafeteria

To send a message to all users connected to the server, type
the following:

    net send /users This server will shut down in 5 minutes.

To run the same command remotely (on server "market_asu"), type
the following (replacing "password" with the password for
"administrator":

    net admin \\market_asu password /command net send
        /users This server will shut down in 5 minutes.
