The game features penguins shooting coloured frozen bubbles to form groups of the same colour so they disappear. The object is to clear the whole screen before a bubble passes the line at the bottom. The game features 100 levels and includes a level editor.

Originally for Linux, Frozen Bubble is now available for Windows, Symbian S60 mobile phones, and even Mac. Besides that, there’s also a browser version of the game that can be played on your browser provided you have the Java Applet installed.

Choose your Frozen Bubble:

• Linux (Mandriva, Slackware, Gentoo, OpenSUSE, Debian, Ubuntu, Fedora Core)
• Frozen Bubble (v1.0.0) Windows port
• Mac OSX port
• Symbian S60 port (2nd Edition and 3rd Edition phones)
• Browser version (Java Applet needed)

So here starts a short guide on various text processing tools.

1) tail
Short Description : output the 10 last lines of files

usage

$tail /your/path/to/file

the above command will display last 10 lines of the desired file. With the following arguments [ or in technical term switch ] you can get more out of it

$tail -n 2 /file/address

The above will display last 2 lines of your desired file [ you can change the value 2 with your own variable ]

$tail -f /file/address

This command is very useful to watch log files of ur Linux Box. This switch append the output with the changes in the file
$tail -v /file/name
This command will print the absolute file address of the file and then will output the last part of that file

2) head
Short Description : output the first 10 lines of files

usage
$head /your/path/to/file

The above command will display first 10 lines of the desired file. The “ head” command can be further customized with following switches

$head -n 4 /file/name
The above will print First four lines of your desired file [ please change value from 4 to your desired number / variable ]

$head -v /file/name
It will print file name and then will produce the head output

3) grep
Short Description : print lines matching a pattern

grep is really nice utility for searching a text withing a long file . It prints that line where the text is found

usage
$grep search_string /file/address
The above command will search for search_string in /file/address named file [ replace the search_string with what you want to search and /file/address with your file address]

4) sed
Short Description : stream editor for filtering and transforming text.

Usage
$sed -e 's:search:replace:g' /file/name

The above will produce output by replacing search string [ it will not change file ]

Now the main tool that is spell checking tool

5) aspell
Short Description: spell checking utility

usage
$aspell check /file/name
will check /file/name for any error and prompt if spelling error found. User then can replace correct spelling and it will be saved in file

$aspell list < /file_name
This will list of misspelled word from /file_name

So this was some shortlisted and commonly used text processing tools . Please note that this was basic text editing strings which are/may_be commonly used . For further info refer to each utilities manual entry

What is a Repository ?
A repository is a collection of list of rpm[s]. It contain various information regarding the rpm like its dependencies etc.

Why to use Yum if I can install RPM using rpm command?
Well if you want to install RPM you have to make sure that its dependencies are also installed . But this is not in the case of YUM you can simply install package with its dependencies. YUM take care of your all install things . Also update feature is not available in the rpm installation method but it is available in yum.

Here are some key features of “Yum”:
• Multiple Repositories
• Simple config file
• Correct dependency calculation
• Fast operation
• rpm-consistent behavior
• comps.xml group support, including multiple repository groups
• Simple interface

Starting With Creating Your Own Repository [Server Side Configuration]

Step First : Check Prequisites
-Have Your Distro CD/DVD

-Check if you have free space on your Hard Disk or not [Total space required vary from Distro to Distro]

Step Two : Copy Disc to Hard Disk
First mount your CD/DVD and copy it to hard disk
cp -avr /cd/dvd/mount/point/ /destination/directory/

Step Three : Intalling CreateRepo Package
Now go to your directory where you copied the files and search for createrepo-*.rpm file * may be different from version to version and system architecture
Install that rpm using rpm command
install using following command
rpm -ivh –aid createrepo-*.rpm

Repeat this step with your all you cd .
Note:- If you want install Repository on your network thrugh ftp or http upload in their respective default directories i.e /var/ftp/pub for ftp server and /var/www/html for http server.

Step four: Run createrepo
Go to the directory where you copied the file and run the createrepo command
createrepo -v .
[please note that “.” {dot} after that command as we are in present directory ]

Now you have done all thing.
Now we will see Client side setting

Client Side Setting For YUM

Create a repo file in /etc/yum.repos.d/ directory [ you can name anything to ur file make sure a .repo extension is added later on]
vim /etc/yum.repos.d/my.repo

add following date in that file

[Myrepo]
name=Any name you want to put
baseurl=file:///destination/directory/
enabled=1
gpgcheck=0

The first line is alias given for your repository . This help to indicate/find that from which repository the package is available.
Second line is name which you can put any thing
Next comes baseurl
base url supports different protocols like file:// ftp:// httpd:// etc. if you are running repository from local pc then give absolute path after file:// . for ftp give ftp://server_ip_or_domain/pub_dir_or_accessable_dir or http://server_ip_or_domain/dir
next line is enabled this specify if yum should enable that repo server for installtion or not 1 is for enable and 0 is for disable
gpgcheck is for checking gpg key. as I don’t required it so I disabled it if you enabled it then you hav to add one more line after that
gpgkey=/your/path/to/key

after this save that repo file and run following command
yum clean all [ will clean yum database ]
yum list [will list the files / packages available on that directory ]

If you find some difficulty in using it please feel free to contact us

Note:- SElinux or Firewall may conflict sometimes [ for ftp and http service ]
Note:- I used RHEL server 5 edition . This process is same for RHEL 4,5 FC [versions I don’t know]
