No tail.exe on Vista HP....

Vista's decision to ship without a native tail.exe makes monitoring logs difficult without GNUWin32 or Cygwin or some other third party utility. This batch (tail.cmd) helps:

@echo off

set file = %1

:top

choice /T 1 /D Y > NUL

for /f "eol=: tokens=3" %%i in ('find ^/C " " %1') do set lastline=%%i

set /a newlastline=%lastline% - 1

set oldlastline=%newlastline%

:top1

choice /T 1 /D Y > NUL

for /f "eol=: tokens=3" %%i in ('find ^/C " " %1') do set lastline=%%i

set /a newlastline=%lastline% - 1

if %oldlastline%==%newlastline% (goto top1) else more +%newlastline% %1 && goto top

[output]:

C:\Windows\System32\LogFiles\Firewall>tail pfirewall.log
