    Default File Shredder?

    I know there used to exist a program that would shred deleted files. I did a search in YAST but didn't see anything. Does this exist in the openSUSE 11.3 repos anywhere?
    My environment is KDE 4.4

    Thanks.

    There are two common command line tools named 'shred' and 'wipe' which will do such jobs.

    Thanks for the reply. This was a part of the right select KDE dialogue if I remember correctly. It was under Mandriva and pretty far back.

    From my looking at the man page for shred if I open a terminal in the directory of interest I can shred and delete the all the files with # shred -u *
    I am hoping this is correct.

    Further reading says shred not effective on ext3 or journaling file systems

    wipe also has some limitations.

    I will continue looking.

    Delete files, then do:

    dd if=/dev/random of=temp.txt; rm temp.txt

    Or if overwriting a specific file:

    dd if=/dev/random of=filetobedeleted; rm filetobedeleted

    "Not effective" refers to the fact that metadata of the respective file may still be found (until it is overwritten as well). The file is shredded and can not be recovered, this should be secure enough for most cases. Per default ext3 / ext4 journals in "ordered" mode, meaning only metadata is journaled, but not the actual file content.

    I suppose you are looking for a KDE-servicemenu for shred, which you will find →here.

    Yes that is it.
    I had to create the ServiceMenu directory but it works as advertised.
