- I am aware that when a file is deleted, the blocks are made 'free' for
- writing, but the files contents can still linger about on the disk; and
- as such can be effectively retrieved with a good program. I've a couple
- of programs (which have saved my life :) that do this.
-
- However: I'm concerned about being able really _eradicate_ a file,
- for various reasons including security.
-
- Does anyone have a program that will do this? A friend suggested that
- I get a program that will open the file and write 'zeros' or something
- to the end of it and then close it. _Then_ /bin/rm the file.
-
- I could see adding this 'feature' to /bin/rm or perhaps writing a
- program called /bin/rrm (_really-remove_) to do this. Hmmm... I wonder
- how government contracts manage this issue...
-
- Thank you.
