Working with command line in ubuntu:
Debian world renowned APT:Advance package tool It was the first tool to properly handle the package dependencies for instance if you need to install calibre in your machine it first install its dependencies and then install the Calibre It has the features of Installation resuming means, while installing the package you loose the internet connection, if you try
to install the package again where you get internet it will resume the installation of that package from where it was before
To upgrade first you need to check for the available update for packages which is done through
$ sudo apt-get update => This will bring you the update 
If you see any update for package using this command now, it’s time to install the updated packages to install the updated packages 
$ sudo apt-get upgrade => This command will install the availabe updates in your system and the output of command line look likes 
Reading package lists… Done
Building dependency tree
Reading state information… Done
The following packages will be upgraded:
cabextract google-chrome-beta icedtea6-plugin language-pack-en
language-pack-en-base language-pack-gnome-en language-pack-gnome-en-base
libfreetype6 libfreetype6-dev libsmbclient libwbclient0 openjdk-6-jre
openjdk-6-jre-headless openjdk-6-jre-lib samba-common samba-common-bin
smbclient upstart winbind xserver-common xserver-xorg-core
21 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Working on the Command Line
Need to get 84.8MB of archives.
After this operation, 623kB of additional disk space will be used.
Do you want to continue [Y/n]?
From the above description you see that 84.4 MB of packages are downloaded but only 623 of additional space will be use means the downloaded package are overwriting to the existing packages 
sometimes when you see 0 not upgraded means some thing is not upgrading to do the upgrade you need to do the distribution upgrade which is done by the following command
$ sudo apt-get dist-upgrade=> This command upgrade the distribution to latest version
on running this command it will upgrade the distribution to newer one, on issuing this command the system will remove the obsolete packages and install the newest one
This command will also ease you to move to latest version of debian without downloading the iso file
updating the system need to be done to fix the bugs appered in the software and  to cope with the security update
$ apt-get install package_name
to install the mysql package I just need to give the MYSQL package name so the system automatically find the packages on the repo and resolve its dependencies and install it into the system
$sudo apt-get install mysql-server => This command install the mysql package 
APT maintains the package cache where it stores DEB files it has downloaded and installed which is usally in /var/cache/apt/archives which take 100 of MB space on the system so we can clean out the package by running the command
$ sudo apt-get clean => This command delete all the cached files from /var/cache/apt/archives
$sudo apt-get autoclean=> This command delete all the aged-out package from /var/cache/apt/archives and provide the space for newer packages
To remove the installed packages form the command line you can just issue the command 
$sudo apt-get remove gedit => This command remove the gedit packages from your system, Removing packages can be dangerous because apt-get remove other dependencies packages which are associated with firefox, so be aware while using the apt-get remove command, for instance if you remove the package $ sudo apt-get remove libgtk2.0.0 which is the main graphical tookit for ubuntu when you issue this command probably the apt-get will remove more than 100 packages from your system, so the moral is  read the APT report carefully before pressing the Y to continue with uninstall.
A straight apt-get remove doesn’t remove the configuration files of the program, so when you later install the package when you remove it before, you don’t need to change the configuration file of the package mean’s that you don’t need to reconfigure the package 
To remove the package along with it’s configuration file issue the following command
$sudo apt-get remove –purge gedit => This will remove the gedit software from your system along with it’s configuration file which perfom the full unistall of the package,
It is hard to find the special package for the system as so many package are availabele with us, so APT provide us a handy tool called apt-cache
To search the package mysql just issue the command 
$ apt-cache search KDE => This will search the mysql package for you from the repository, you may see the result that package name even don’t have the kde name so how apt-cache search it, the simple answer the package description contained the name KDE so from the description parameter apt-cache search tool find the KDE packages
we can filter the output for apt-cache search in many ways 
$ apt-cache -n search kde => -n tells the command search the KDE package only by name not to look at the description, with issuing this command the search has reduced from 1000 to 100 results
$sudo apt-cache showpkg kde => This command display the package information just like below
tulsi@surfer:/var/cache/apt/archives$ apt-cache showpkg kde
Package: kde

doug --- off the record

I don’t always blog using Ubuntu and I don’t always blog using a blogging client instead of using the web or in a browser.  But, when I do, there are two tools that I use and really like.

But when I do, I use Blogilo and Shutter.

Shutter is a really handy full featured screen capture tool.  It’s got your typical options for what to grab with both simple and advanced interfaces.  

One of the features that I find particularly helpful is the ability to zoom in after you’ve selected an area.  Sure, you could and probably should before taking the shot but planning isn’t always in the books for me!  Another helpful feature is to be able to capture the cascading menu from a particular application.  Invaluable if you’re creating instructions for others.

Once you’ve grabbed an image, it’s always nice to be able to edit it…

The Robot Fix

Do you have a problem with a certain alien from the planet Krypton? Are you a hard working multi-billionaire, super powered human, or evil deed enthusiast? Do you spend day and night building evil robots, conducting crazy genetic experiments to create horrible monsters, fabricating mind control devices or doomsday weapons, concocting plans to seize the world’s gold, water, air, or cupcake supply only to be foiled by a pesky Kryptonian? Or are you a friend with a Kryptonian and want a weapon in case your friend loses control of his or her mind or body due to mind control or body switching? Well you’re in luck. You can create your own Kryptonite that will end your Kryptonian problem. This green-glowing rock is the only weakness of Kryptonians. Well, magic is another weakness, but magic is really hard to learn and all you have to do with Kryptonite is hold it.
