Hi methyl,

Thanks for your response.

The current date and month is referring to today's date and month as this script will be scheduled to run daily and monthly.

I've tried your method and it seems to be OK. Please see below.

Code:
# TODAY=`date +'%a %b %e, %Y'`

# echo $TODAY
Tue Sep 14, 2010

However, as shown below, some of the dates are not always in 2 digits, then your method might not work when the date is smaller than 10, single digit.

Code:
Sample log data:
----------------
13:36  Sun Dec 8, 2009.  Reboot:  (by root)
13:56  Sun Dec 10, 2009.  Halt:  (by root)
15:12  Sun Dec 27, 2009.  Reboot:  (by root)
13:46  Sun Apr 1, 2010.  Halt:
14:43  Sun Apr 8, 2010.  Halt:
17:28  Sun Apr 18, 2010.  Reboot:  (by root)
18:15  Thu Jul  1, 2010.  Reboot:  (by  root)
12:01  Mon Aug 30, 2010.  Reboot:  (by root)

Please kindly advice.

Thanks.

Cheers.
