Deleting without using the recycle bin
By default, when you delete a file in Nautilus (the file browser of Ubuntu), files are moved to the Trash.
This is not always desirable, especially for large files.
Here's how to really delete the files:
Keyboard shortcut
Just type
Shift + Delete to delete the selected files.
Nautilus context menu
Type in a terminal:
gconftool-2 --type bool --set/apps/nautilus/preferences/enable_delete "1"
(You can also make this modification using the program
gconf-editor)
You can now delete files directly (right click on the object and press Delete)
Note
It is quite possible to use both methods.
You can delete a file directly from the command line by typing
rm filename in a terminal.
Please do not remove anything, the operation of the file under GNU / Linux makes it almost impossible to recover deleted files.
