WARN

The WARN command enables you to send an urgent operator message to jobs or sessions. The message interrupts any current pending read or write in progress.

Syntax



   WARN {@

         [#]Jnnn

         [#]Snnn

         [jsname,]user.acct} [;message]

Parameters

@

Specifies that all users receive the message, including those running in quiet mode.

#Jnnn

Specifies a job number assigned by the system for the job that is to receive the message. Only jobs submitted on interactive devices can receive messages.

#Snnn

Specifies a session number assigned by the system for the job that is to receive the message. Only jobs submitted on interactive devices can receive messages.

jsname, user.acct

Specifies the names of the job, session, and user to receive the message, and specifies the account name under which they are running. (These names are the same as those entered with the JOB or HELLO command.)

If several users are running under the same job and session identity, the system sends the message to all of them.

message

Specifies the message text, consisting of any string of ASCII characters containing no more than 67 characters. Pressing Return terminates the message. The default is that no message prints.

Operation Notes

Usage
You can enter this command from a session, a job, a program, or in break mode. Pressing Break does not affect this command. You can enter this command only from the console; however, you can enter this command from your terminal if your system administrator has used the ALLOW command to enable you to enter the WARN command.
Quiet mode
A user can run a session in quiet mode, which suppresses messages from other users; however, the WARN command overrides quiet mode and also overrides a block mode screen.

Example

To send a WARN message to all sessions, followed by a WARN message to session #S51, enter:



   :WARN @;THE SYSTEM WILL SHUTDOWN IN 5 MINUTES. PLS LOG OFF.

   :WARN #S51;LAST CHANCE TO LOG OFF GRACEFULLY.
