====== Getting a wipe action in the menu ======

Adding wipe to your Nautilus context menu is useful in making it so that you can securely delete any number of files and/or folders at one time simply by selecting them, right clicking, and clicking wipe. Before you can add wipe to the context menu you must have nautilus-actions and wipe installed. To install them on a Debian based system, at the terminal, simply type:


    sudo apt-get install wipe
    sudo apt-get install nautilus-actions



When you install nautilus-actions a GUI based tool will be installed to allow you configure context menu additions. Access it by, at the terminal, typing:
nautilus-actions-config

Adding the wipe command to the context menu is now very straight forward. The following instructions were written for nautilus-actions 1.4.1:


    1. Click the +Add button.
    2. For the label enter: Wipe.
    3. For the tooltip enter: Use the wipe utility to securely delete the file(s)/folder(s).
    4. For the path enter: wipe
    5. For the parameters enter: -rf %M
    6. Go to the Conditions tab and select the radio button labeled "Both" for when the command should appear and check "Appears if select has multiple files or folders"
    7. I left everything else at their defaults. If you don't want to do any further customization just hit OK and close the configuration tool.


8. You can select an icon, I prefer the gtk-dialog-warning icon.
The parameters to wipe, -rf %M, causes files and folders to be deleted without prompting. Due to the -r command, if there are files or subfolders in a selected folder they will also be wiped. If you would like for files to be wiped even when write permission is not set change the parameters to: -rcf %M.

The final step is to reset nautilus. At the terminal type:


    nautilus -q
    nautilus



You will now have a command for wipe in your Nautilus context menu that allows you to securely delete any number of files and/or folders in two clicks.
====== Using a script with output ======
The above wipe action doesn't tell you anything on how progress is going and wiping a lot of file on a usb stick take a while.

Therefor this little tweak to show what is going on and as an added bonus it also ask you before trashing your important files :-D.

Start out by making a file called "wiper.sh":
<file>
#!/bin/sh
file=$1

$(zenity --title="Wipe $file" --question --text="Are you sure?")
if [ $? -eq 0 ]
then
	gnome-terminal -e "wipe -qQ10 -rfi $file"
	exit 0
 else
	exit 0
 fi
fi
</file>

Make it executable:

<code>
chmod +x wiper.sh
</code>

Change the settings for the wipe action in nautilus-action-config:

{{:indexes:screenshot-edit_action_wipe_.png|}}

And bounce Nautilus:
<code>
nautilus -q
</code>
