General :: Delete The File And Its Actual Associated Data?

May 12, 2011

I'm confused about "hard link" feature. I've been learning from my UNIX Academy DVDs training that hard links to a file can be many and each of them is an effective filename for the associated data. So let assume that we have some very sensitive data in a file and we want it to be deleted and file has 20 links. I "delete" a file, but in fact I deleted only one "name" of it. My understanding from the training that data is still there until we delete the last associated hard link. But how can I find the names of all of them? If we have the names, they can be removed one by one. Or may be there's command that can trace all the "names" and remove them at once?

General :: How To Create Disk Image Of Actual Data

Nov 15, 2010

Suppose I have a 80 GB hard disk (sda) with 4GB of contents. Using a dd to copy to a different disk

Code:
dd if=/dev/sda of=/dev/sdb
copies all the contents (including free space). So sdb also needs to be 80GB.

You will notice that in VMWare or VirtualBox disk images, it is possible to set the disk to use only the amount of space of actual data. So a 80GB virtualbox/vmware image with 4GB of contents will be 4GB.

Is it possible to do that with an actual hard disk (sda) image? I want to create an image of an actual hard disk, copy it to DVD and transport it (in mail) for restoration on another computer (having same hard disk).

General :: Redirect From A File Into An Actual For Loop?

Apr 11, 2011

I multi-boot several Linux distributions with an assortment of additional data partitions. I get frustrated whenever fsck is forced during boot. (It ONLY happens when I'm in a hurry don't you know...) So I wrote a script to automate forced fscking when I do have the time. (And/or while I'm doing something else in another workspace.

Because I multi-boot, I've learned that udev doesn't always assign the same device name to each drive for all distributions. I've had the same partition identified as hda5, sda5, & sdb5 by different distributions (without doing anything to affect the boot order) So my solution is to keep a list of partitions in a specific file on each distro with valid device names according to that distribution's udev process. Actually I'd use LABEL= instead but the labels don't show up in /etc/mtab, and I like to make sure a partition isn't mounted before I try to fsck it.

I can make this work in a for loop using cat. But I've seen so many things about NOT using cat that I wanted to rebuild my script. I can make this work with a redirect instead of cat via a while loop, But I "LIKE" old style for loops. But I can't seem to find a way to make a redirect work with one. I thought this might make a good first �LinuxQuestions.org� question. I'm also open to any other suggestions on better/alternative methods... Is it possible to redirect from a file into an actual for loop?

My script is as follows:

Code:

#!/bin/bash
# FsckEm I script to force file system checking on unmounted ext2/ext3/ext4
# partitions in preselected list. FsckEm accepts no options. Partition

General :: Any Way To Change Actual File Names Using Amarok?

Jan 9, 2010

I use amarok 2 and I have a lot of files that are titled "Track #.mp3", in Amarok I have changed them to see as the real songs but the actual files are still the same. Is there a way to change the actual file names using amarok to match the tags I have inside of amarok? The reason why I'd want to do this:

1. If my home folder becomes corrupt I don't have to redo 100's of songs (I have a backup but none the less
2. If I ever decide to use another program or if I'm in W7 using Windows Media Player classic it'd be nice to have it recognize the correct files without having to double up on the tag editing

If this isn't possible I'm going to wishlist it because I think it's functional and having a bunch of Track# files is a pain but impossible to get around when you have a lot of mix cd's.

Software :: Restore The Actual File From My_file.c,v File?

Jun 15, 2011

I am browsing our repository and I want to get this folder but all of the files there have ",v" in the end of their filenames and if you open each file, they have some written data which are headers for version control before the actual content of the file. I want to extract the actual content to make the file my_file.c,v --> my_file.c. Is there a command to do this?

I am having lock error and permission errors so I cannot checkout manually using CVS.
