Need some help writing a script
Need some help writing a script.....trying to have the script query the computer name and then run a command based on what is the resulting computer name.
For instance, these are the computer names:
DESKTOP
LAPTOP
LAPTOP-BACKUP
If the result is DESKTOP run
route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF 37
Then quit
If the result is LAPTOP run
route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF 24
Then quit
etc with LAPTOP-BACKUP, the IF # will probably be different
This is to help script VPN connections, so there will be different files based on different networks.
I have to delete the route later, but that command is easier
route delete 192.168.1.0
So that is not computer dependent.
The super bestest thing in the entire world would be if the computer name, and IF (interface) number were tied together. The network address and mask should never change. That way if I change computers or IF changes, I make one change opposed to a bunch of files.

DESKTOP
LAPTOP
LAPTOP-BACKUP

route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF 37

route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF 24

I knew it was going to be simple for someone. I am learning a little more about this. I am going to test it on the other computers and then award points. The simplicity of this is absolutely elegant. :)
A slight enhancement. Adjustments made to (1) exit as soon as a match is found in the TXT file, rather than continuing to read lines from it even after a host name match was found, and (2) display a warning message if a computer name is not found in the TXT file in case that needs to be addressed?
@echo off
for /f "tokens=1,2" %%a in (Route_Stns.txt) do (
if /i "%computername%" equ "%%a" (
route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF %%b
exit /b
)
)
echo *Warning* - Workstation not found in routing table, please contact IT.
pause
Another improvement: Directly search the host name.
@echo off
for /F "tokens=1-2" %%a in ('findstr /c:"%computername%" Route_Stns.txt') do set inf=%%b
if defined inf (
route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF %inf%
) else (
echo *Warning* - Workstation %computernamer% not found in routing table, please contact IT.
)
You could also consider to use a VBScript.
Dim arrComputer(99, 1)
Set WshShell = WScript.CreateObject("WScript.Shell")
Set WshNetwork = CreateObject("WScript.Network")
strComputerName = WshNetwork.ComputerName
arrComputer(0,0) = "DESKTOP"
arrComputer(0,1) = "37"
arrComputer(1,0) = "LAPTOP"
arrComputer(1,1) = "24"
arrComputer(2,0) = "LAPTOP-BACKUP"
arrComputer(2,1) = "30"
For i = 0 To UBound(arrComputer)
If arrComputer(i,0) = "" Then Exit For
If UCase(strComputerName) = arrComputer(i,0) Then
Wscript.echo "Creating route for IF " & arrComputer(i,1)
strCommand = "route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 IF " & arrComputer(i,1)
Set objScriptExec = WshShell.Exec(strCommand)
strResults = objScriptExec.StdOut.ReadAll
strResults = strResults & objScriptExec.StdErr.ReadAll
Wscript.echo strResults
Exit For
End If
