Shred utility

Hi experts.

We have a HP-Unix server, we deleted some files and folders from the server. Is there any utilities that we can use to ensure those deleted files and folders are not recoverable? We used rm command to delete these files.



Cheers,
RTSmilie

Is this for a high-security envrionment? I hope not. Most shredding will not work for filesystems that do not (for various reasons) immediately wrote over a deleted file.

FileBuzz - Find Software Fast has some simple shredder utilities that will keep an uninformed manager happy but will probably never pass a security audit.

You can google for 'file shredder' - Linux has one called shred. It is opensource, so you can compile it if you have gcc.
