如何使wall的信息只发给root用户,不发给终端!
不将wall改名 ,有什么好的办法吗

各位,报谦,我没有说明白,不是手工mail,而是系统发生了故障,

比如一个电源坏掉了什么的,这样系统就会向终端不停的发wall信息

搞的终端都不能用了,有什么办法能使wall信息不发给终端,

除了将wall命令改名字!

see whether this message is wall by cron.
if it is, try 'crontab -e'

you use the command #crontab -e to remove the record about the powerfail,

As far as I understand it,
if the power problem is still there ,
the system will detect it and put it back in.

I guess it's the /usr/lpp/diagnostics/bin/diagd daemon that writes this message to crontab,
so,you'd better repair the power supply,
the wall message will not appear.

this is the thorough method.

0 00,12 * * * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.

the power message will be as this  ?

if you don't repair the power,
you can edit the crontab record as below,

0 0 31 12 * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.
