Regular Expression Problem

chris1234 · #1 (**permalink**) 04-01-2008

this is how my xyz.log file loooks like :-

[30/Dec/2008:12:03:07] info ( 816): CORE1116: Sun ONE Web Server 6.1SP5 B08/17/2005 22:09
[31/Dec/2008:12:03:08] info ( 817): CORE5076: Using [Java HotSpot(TM) Server VM, Version 1.5.0_11] from [Sun Microsystems Inc
.]
[01/Jan/2008:12:03:08] info ( 817): WEB0100: Loading web module in virtual server [http-google] at [/abc]
[02/Jan/2008:12:03:08] info ( 817): WEB0100: Loading web module in virtual server [http-google] at [/abc]

Code:

perl -MPOSIX -i.bak  -ne 'BEGIN{

 $d=strftime("%d%m%Y",localtime time-60*24*60*60);
 @m{qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec)}=("01".."12")}

 print if m"^(\d+)/(\w+)/(\d{4})"&& "$1$m{$2}$3" gt $d' xyz.log

I am trying to keep the last 60 days data and delete everything else but for some reason its deleting everything in xyz.log instead of keeping the last 60 days and deleting the rest.

Any info will be really appreciated. I am new to regular expression.
