let's say in my office i have 20 networked sun boxes named host1 through host20. i am currently logged in as root at some random machine, which we will say host13 for this scenario's sake. now, is there any way i can send a text message of some sort over the whole network to all logged in...

is there a command to send all terminals a message. i tired wall, but it only sends the message to who ever is logged in at a terminal. i need a command to send to every terminal no matter if someone is logged in or not.
Thanks!

So I've been tasked with creating a shell script to run in a cron every few minutes to check duplex settings on my eth0 nic card. I would like for the server to send a wall message to whoever is on the console or in a terminal session. Below is what I have so far.

I do have a question about the great cyber wall of certain countries, like the UK for example. For years I just fetched once a week a public podcast that recently answered "notukerror", by chance I read just this weekend on slashdot about this topic. Does this mean the efforts enhanced by the EME... (4 Replies)

wall
wall(1M) System Administration Commands wall(1M)NAME
wall - write to all users
SYNOPSIS
/usr/sbin/wall [-a] [-g grpname] [filename]
DESCRIPTION
wall reads its standard input until an end-of-file. It then sends this message to all currently logged-in users preceded by:
Broadcast Message from ...
If filename is given, then the message is read in from that file. Normally, pseudo-terminals that do not correspond to rlogin sessions are
ignored. Thus, when using a window system, the message appears only on the console window. However, -a will send the message even to such
pseudo-terminals.
It is used to warn all users, typically prior to shutting down the system.
The sender must be superuser to override any protections the users may have invoked See mesg(1).
wall runs setgid() to the group ID tty, in order to have write permissions on other user's terminals. See setuid(2).
wall will detect non-printable characters before sending them to the user's terminal. Control characters will appear as a " ^ " followed
by the appropriate ASCII character; characters with the high-order bit set will appear in "meta" notation. For example, ` 03' is dis-
played as `^C' and `372' as `M-z'.
OPTIONS
The following options are supported:
-a Broadcast message to the console and pseudo-terminals.
-g grpname Broadcast to the users in a specified group only, per the group database (see group(4)).
ENVIRONMENT VARIABLES
If the LC_* variables (LC_CTYPE, LC_TIME, LC_COLLATE, LC_NUMERIC, and LC_MONETARY) are not set in the environment, the operational behav-
ior of wall for each corresponding locale category is determined by the value of the LANG environment variable. See environ(5). If LC_ALL
is set, its contents are used to override both the LANG and the other LC_* variables. If none of the above variables are set in the envi-
ronment, the "C" (U.S. style) locale determines how wall behaves.
FILES
