As best practice; I recommend to keep all scripts in a folder at the base of the %systemdrive% or C: drive and include it in your system %path% variable. This makes it easy to take your tools with you, when you redo your laptop or desktop. I personally use a folder called ‘sys’, but you can select your own. Just be sure to include the folder in your %path% variable.

Even if you put all your files in a particular folder sometimes your just looking for that particular file in the path. So I have written a Windows version of the UNIX ‘which’ command. Just copy the script below and save it as ‘which.cmd’ in your ‘sys’ folder.

Copy and Paste the script below into notepad and save it as “which.cmd”

@echo off
rem /
rem / which.cmd - 110108 - bohack.com 2008i     /
rem / Windows version of the UNIX which command /
rem /
setlocal
if [%1]==[] goto :errhand
set whichpath=%~dp$path:1
if [%whichpath%]==[] goto :end
echo %whichpath%%1
goto end

:errhand
echo.
echo Usage: %0 (filename to search in path)

:end
endlocal

Once it’s started via the command of ‘pingmon servername’. It will echo the time it started monitoring, then the alive time of a successful ping back. Once the host goes dead, it will echo the time it went dead or lost ping. Then it will echo the time it has gone alive again and quit. Simple batch script with one purpose, to make the administrator’s life simple.

Just copy and paste the script below into notepad and save it as “pingmon.cmd”

@echo off

rem Bohack - pingmon.cmd - 2002i

if {%ipname%}=={} (GOTO :errhand)
