Can anyone help me!

Hi All,
 I am new to Perl, Currently I'm facing on problem. I used
to run perl
programs on Windows. I don't know how to write a code: which
will
extract the last line of an output generated by a command.
the command
is related to query on Windows Registry.

Usually We used to query the Valuename for the given Key or
subkey,
using the following command, in the command prompt.
C:Documents and Settingsccd1101>reg query
HKLMSOFTWAREGoogleNavClient /v installtime

And in the console it gives an output like this:

! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINESOFTWAREGoogleNavClient
    installtime REG_SZ  1148018321

But I am not able to know how to extract the last line, May
be the
last line is a balnk line or the last line is 
 installtime REG_SZ  1148018321

I am interested in extracting the last value that is
1148018321, It is
the 'Value data', we call it in registry while installtime
is the
'Value name' that I can get using split, but how to get the
last
printed line not the last blank line,is the major concern.

Please provide me a solution.

Please provide us with the code you have written so far. You
post
gives me the impression that you have some code written.
If you want a solution you can ask at jobs.perl.org and pay
someone.

Here is some pseudo code for free:
- Capture the output of 'reg query' into a list.
- grep for the 'installtime' line into a new list
- split the last element of that new list to get the data.
