wipe and journalling file systems (was Re: Deleting a Folder)

It won't work on journaled filesystems, though. The shred(1)[0] man page states: In the case of ext3 file systems, the above dis- claimer applies (and shred is thus of limited effectiveness) only in data=journal mode, which journals file data in addition to just metadata. In both the data=ordered (default) and data=write- back modes, shred works as usual. Ext3 journaling modes can be changed by adding the data=something option to the mount options for a particular file system in the /etc/fstab file, as documented in the mount man page (man mount). I'm sure that the same reasoning that says that shred(1) will shred files on default ext3 mounts will also allow wipe to shred files. Except, of course, modern hard drives do transparent sector remapping, so even shredding an ext2 partition can't guarantee total safety. I've Googled for the curie temperature of hard drive platters, but have found only conflicting non-expert numbers. Heating the media in a pottery kiln should suffice. A MAPP gas hand-held blow-torch (5300F, 2930C) should also do the trick. [0] shred is in coreutils. - -- Ron Johnson, Jr. Jefferson LA USA Is common sense really valid?

Deleting a Folder
Lets say I have a folder that has about 400 items, from mp3 to xls sheets, to mpeg movies to .pdf files, all kinds of media types.. What command in Linux, can shred the whole folder and ALL of its contents, without me going into the folder and hand deleting items by group type. Just looking for a quicker method, have attachment folder for emails, it fills up quick. eg: folder: attachments 402 items...

Re: Deleting a folder
I'm not certain but I think you can use this command:rm -R [folder name]check the man page...you can also remove files that begin/end with specific strings.-- Jon

I sometimes use the 'shred' command, typically like this : $ shred -uz top_secret.txt or $ shred -uz top_secret/* I guess then as you say a rm -R top_secret would do away with the directory nicely too. Not quite what the OP wanted I guess (shred) but it works for me. HTH. Regards, Pete. signature.asc Description: Digital signature

I did not know that the shred command could remove subdirectories, only files. That is why I only mentioned 'wipe'. Neither tool will work on journaled filesystems. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
