If you are new to Apple Mac OS X, you will be frustrated to find out how to switch between same application window like Microsoft Windows Alt + Tab.
By default, the OS X only does application window switching instead of active window switching with the short cut key Apple + Tab.
Just bought a new Nokia E71 mobile phone, the first thing i wanna do was to find out how to sync all my contact and calendar with my Macbook.
Many windows user may know that F2 is the shortcut key to edit a cell on Microsoft Excel. I run native Microsoft Excel on Apple Mac OSX to do my claims, report, database and etc. Sometime it’s annoying on cell editing, especially when you want to edit the cell, need to move your mouse and double click.
Is there any F2 like short cut key on OSX Leopard’s Microsoft Excel?
Information displays from phpinfo() may provide resourceful information to attacker, such as file patch, web server environment, php modules, web server modules and etc. It’s better to disable phpinfo() function on your webserver.
there are over thousand emails queue in our mail server, even though I have configured email frozen more than 10 days automatically delete/remove, but it seem like doesn’t work as expected.
here is the work around if you plan to do it manually.
start with listing email queue in the server, by using the command exim -bp, it will list all the email currently queue in the server. but my only concern is frozen email in the server, which I would like to manually clean it from the queue. let try something here,
exim -bp | grep frozen
18d 24K 1JhiI4-00096B-OW <> *** frozen ***
18d 2.3K 1JhiII-00097Y-8s <> *** frozen ***
16d 2.8K 1JhiKM-0009AL-9M <> *** frozen ***
15d 2.3K 1JhiLO-0009Bs-EF <> *** frozen ***
15d 2.5K 1JhiLS-0009Bx-O2 <> *** frozen ***
12d 2.7K 1JhiNm-0009S5-AQ <> *** frozen ***
10d 3.3K 1JhiPv-0009aN-Vu <> *** frozen ***
10d 24K 1JhiQ9-0009as-4R <> *** frozen ***
There are the emails currently queue in the server, and now you might want to check why did the email was queue in the server by exim -Mvl

If you want to remove all the email from queue more than 18 days, try this command;
