Sends a message to a user.


Msg{UserName | SessionName | SessionID | @FileName | *} [/server:ServerName] [/time:Seconds] [/v] [/w] [Message]

The name of the user you want to receive the message.

The name of the session you want to receive the message.

The numeric ID of the session whose user you want to receive a message.

@ FileName
Identifies a file containing a list of user names, session names, and session IDs that you want to receive the message.

Sends the message to all user names on the system.

/server: ServerName
Specifies the terminal server whose session or user you want to receive the message. If unspecified, /server uses the server to which you are currently logged on.

/time: Seconds
Specifies the amount of time the message you sent is displayed on the user's screen. Once the time limit is reached, the message disappears. If no time limit is set, the message remains on the user's screen until the user sees the message and clicks OK.

Displays information about the actions being performed.

Waits for an acknowledgement from the user that the message has been received. Use this parameter with /time:Seconds to avoid a possible long delay if the user does not immediately respond. Using this parameter with /v is also helpful.

The text of the message you want to send. If no message is typed, you are prompted for it or standard input (that is, stdin) is read for the message. To send a message that is contained in a file, type the less than (<) symbol followed by the file name.

Displays help at the command prompt.

  • If you do not specify a name for the user or session, msg displays an error message. When specifying the name of a session, it must be an active one.

  • The user must have send message access permission to send a message.
