Having worked with Microsoft environment for 8+ years , i thought of giving Linux a try . So i installed Ubuntu in my system and just walking through its features and configuring my mail client. While browsing through sites i found that flash plug-in was not installed in my browser . So i went on searching Net how to install it . With Microsoft its a single click at Setup files which will do the rest but here i need another couple of steps and there are different ways through which i can achieve the same thing. Its Really interesting which i thought of sharing with you guys . Will share you the rest of my User Experience with Linux in Coming years.
Download Adobe Flash Player 9
Go to http://www.adobe.com and click on the Get Adobe Flash Player button. Make sure you use a browser from your Linux desktop; if you use a Windows browser you will be redirected to the Windows version of the Flash Player 9. Provided you use a Linux browser, you will be redirected to the download page of the Linux version of the Flash Player 9. On the download page you can choose between a Flash Player .tar.gz file and a Flash Player .rpm file. Select one of them (it doesn’t matter which one) and download it to your computer (in my case I downloaded .tar.gz to /home/aashath/Desktop).
Installing Without Command Line
Yes, you can install this without troubling yourself to open the command line at all. (Command line instructions are below).
Right-click on the downloaded installation file and choose “Extract Here” from the menu.

Now open up the new folder and double-click on flashplayer-installer. When prompted, choose to “Run in Terminal”

You’ll have to click inside the window and hit the Enter key and then the y key at the prompts. (Make sure you have Firefox closed)

Now your Flash player should be working just fine.
Installing from the Command Line
If you prefer to install from the command line, you can run the following commands to download and install flash player. Make sure you’ve closed all instances of Firefox before you start this.
wget http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_9_linux.tar.gz
tar xvfz install_flash_player_9_linux
cd install_flash_player_9_linux
./flashplayer-installer
Verifying Installation
Type about:plugins into the address bar, and verify that you see Shockwave Flash in the list.
Thats all ! you have successfully installed flash player now.
