How to move taskbar to bottom position as in Windows

I know this question is for 14.04, but as this is one of the first results for "moving taksbar to bottom", I think it will be helpful to others like me who want to do this on Ubuntu 16.04:

Just execute the following command:

gsettings set com.canonical.Unity.Launcher launcher-position Bottom

Or, if you prefer something more detailed, and more options, install unity tweak tool, as explained in the accepted answer.

In case you want to use unity you can achieve similar thing:

1. Install unity-tweak-tool:

   sudo apt-get install unity-tweak-tool
   

2. Run unity-tweak-tool and in Launcher choose autohide.

3. Install cairo-dock using:

   sudo apt-get install cairo-dock
   

4. Run cairo-dock and add the applications in the dock you wanna use.

In case you wanna use gnome you can use gnome-session-flashback and delete the taskbar above and you can achieve desired functionality:

sudo apt-get install gnome-session-flashback

If you're using XFCE, you simply right click the panel -> Panel preferences. Then drag it whereever you like. Like so:

• Go to ‘System Settings > Appearance’
• Select the ‘Behavior’ tab
• Find the section headed: ‘Show the Menus for a Window’
• Check (click) the circle next to ‘In the window’s title bar’
