Batch file question

I need to add hostname resolution to my getMAC.bat script. Right now it
only works with IP addresses. I found this:
http://www.robvanderwoude.com/files/hostname_nt.txt script that gets
the hostname for a given IP, and ECHO's it to stdouot. How can I
integrate that that for loop into my existing script?

@echo off

set ip= %1
if /i "%1" == "?" goto help
if /i "%1" == "/?" goto help
if /i "%1" == "-h" goto help
if /i "%1" == "--help" goto help
if /i "%1" == "/h" goto help
if /i "%1" == "" (goto start
)else goto auto

:start
cls

Try this:

set ip=%1
if "%1"=="" goto start
echo %1 | find "." > nul
if ErrorLevel 1 (goto help) else (goto auto)

:start
echo.
echo Clearing ARP Cache . . .
netsh interface ip delete arpcache

echo Enter IP address of remote computer:
set /p ip=
if %ip% =="" goto end

ping %ip% | find /i "bytes=" > nul || goto fail
arp -a %ip%
goto eof
===================
:auto
ping -n 1 %1 | find /i "bytes=" > nul || goto fail
arp -a | findstr "%1"
goto end

Thanks, but that didn't work. It works with IP's like the one I wrote,
but not hostnames. The problem is caused by the arp command not
supporting hostnames. What I think needs to be done is the hostname
given needs to be put into a variable, and then the IP needs to be
found for that hostname and put into another variable. If the 2
variables values are ==, then run the arp command for that variable.

Thanks,

Tony

What you write is incorrect: arp.exe works with IP addresses
and also with host names - see below.

Your statement "If the 2 variables values are ==, then run the arp
command for that variable." is unclear. What "2 variables"?
