How to broadcast a message to all user's.

Tarts · 10-02-2003, 08:55 PM

Hello!

I would like to broadcast a messsage to all user's on any terminal's.
I've looked into 'talk' and 'write', I was looking for something similar the way shutdown work's: 'shutdown -r now "The system is going for a reboot"'

Any advise on a way to accomplish this goal of mine?

Thank you, Tarts.

#> wall file.txt

Thank's alot!

Allow me to show you the result's:

Code:

#!/bin/bash
MODTIME=/var/log/modfile
TMP=tmp

find / -mtime 2 -o ctime 2 &> $MODTIME
echo 1> /dev/null
echo "Mirrus: Check '/var/log/modfile'." &> $TMP
wall $TMP
rm $TMP
exit 0

Next learn 'crond' and have it run on specified interval's!

Thank's!

I thought you can straight away wall on the command line...

ie: wall Hey you people!!!

It worked on mine in Mandrake 9.1.

[root@smoker dale]# wall "hey you people"
[root@smoker dale]#
Broadcast message from root (pts/1) (Fri Oct 3 02:43:04 2003):

hey you people

[root@smoker dale]#

he he he he he he. I learned something new.

Thanks.

My experiences:

micxz@mars:~> wall message.txt
wall: will not read message.txt - use stdin.
micxz@mars:~> cat message.txt | wall

Broadcast Message from micxz@mars
(/dev/pts/4) at 1:21 ...

Hello'
This is a cool thing you can do;

Works nice;
also:

micxz@mars:~> wall
testing typing now cntrl-D twice fast;

Broadcast Message from micxz@mars
(/dev/pts/4) at 1:21 ...
testing typing now cntrl-D twice fast;

Works also;

This does not work on my system, wall need's a file, by default it supposed to read from 'stdin', but this does not work, i'm sure there's a way to redirect or something....

{edit}

#wall
Hello!

then type ctrl d
{edit2}

#echo "Hello users, the date is `date`" | wall

On my Ubuntu 10.04 I use something like:

echo Please log off now!!! | wall

Wow! You dug deep to find this old thread. It's only 7 years old.

GazL · 09-28-2010, 06:26 PM

1) Why are you resurrecting a 7 year old thread?

2) You didn't even get the command right! You'd end up getting a "Please log off now" command not found, doing that!

Not exactly an auspicious first post.

Gee wiz dude! I am glad that fellow actually posted that. With quotation marks it almost works; but I haven't seen anyone post a good answer yet. Is this an unauspicious first post too? And, the essential CLI should still apply even 7 years later, no?

This works here:

Code:

wall -n "please log off now"

It even does a pop up in KDE4. One of those "notify" thingys. lol
