HIDDEN EXTRAS

In addition to the “srm” command in the nuke script, which securely erases the home folder, you may have noticed that there are two other commands: “sfill” and “smem.” Remove the # at the start of these lines to overwrite the free space in the / home folder, and clean any files in the Pi’s virtual memory (RAM) respectively. This takes much longer than the “srm” command on its own, but is a good deal safer.
