Gnome (GUI) trash is usually in: ~/.local/share/Trash

sudo apt-get install trash-cli # save yourself the agony of rm ~, use trash

trash filename.txt

trash-list 2013-09-20 12:34:56 /tmp/filename.txt

restore-trash

trash-empty #remove all items from trash

weird, trash vs trash-put, trash-list vs list-trash, restore-trash vs trash-restore
