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 } [;message]
{[#]Snnn }
{[jsname,]user.acct}
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.
