A script batch to send a Message to WKS in the LAN

i need a batch script to send an Alert message to One or many computers in the LAN

the script should take some variables that the user will key in which are:
The Number of WKS to send the message (Var  1)
The Names of the WKS to send the messages (Var2)
The Message to be sent (Var "3)

and the script will use the command msg to send var 3 to WKS in VAr 2

I hope i made this clear . the script should be enough User friendly that why I see a dialogue to collect the variables

Thx

What is Number of WKS for?

How about this?
set /p NumWKS=Number of WKS?
set /p NameWKS=Name of WKS?
set /p Msg=Message?
msg %NameWKS% %Msg%

If you want your script to run interactively you could go for comma separated values in your computername string. For example:
$message = read-host -prompt "type your message here"
$computername = Read-Host -Prompt "type a computername or multiple separated by comma"
$session = "*"
foreach ($computer in ($computername -split ',')) {
msg $session /server:$computer $message
}

Open in new window


If you want to have a parameterized script you could do something like this, allowing you to call this script with 1 or more computer names:
param (
[string]$Message,
[string[]]$ComputerName
[string]$Session = '*'
)
foreach ($Computer in $ComputerName) {
msg $session /server:$computer $message
}

Do neither of the two script options I provided above work for you ?
gazambeyIT CONSULTANTAuthor Commented:
Yes the scripts are working fine . I choose the Interactive one . The Only thing for certains Machines there is one Registry key that have to be changed otherwise there will be an error
