How to empty Trash in Ubuntu (UNR)

Tested in Ubuntu Netbook Remix 10.04

Two ways to empty trash
1. Complete it manually in Terminal
     sudo rm -rf /home//.local/share/Trash/files/*

2. In "Files & folders", click any folder icon to open File browser. Click "Go" in the toolbar, then select Trash. Simply click the "Empty Trash", your Trash folder will be empty.
