http://www.linuxforums.org – Hi all, It is possible to make a system setting somewhere or install code so that when a file is deleted or moved, regardless of how, ie: using any means a shell cmd or a desktop application, the file is securely deleted? I typically use gnome desktop and when I delete a file I want to know for certain it has been deleted, erased, all data gone... etc. While I am aware of shred, it's cmd line only and doesn't apply to my question. I want to have any file that is being deleted or moved to wipe the source disk areas. (HowTos)

Hi

I want to delete a line from a txt file for which the line number is user input. Say when user selects 19, the 19th line would be deleted from the file. Can anyone please provide me with a sed one liner for the same... I tried sed -i.

I have been deleted the file

rm -rf ./Desktop/myScript.sh

I think it's possible to recover this file because rm command just remove temporarily. How can I recover deleted file on Mac OSX?

Thank you a lot.

Earlier I had my N7 plugged into my PC and I tried to delete some files from there.

The files didn't get deleted, and they now appear to be stuck. I can't delete them via the PC, while a file manager, or even via the terminal with root permissions. Every time it just tells me the delete failed.

Has anyone else had that happen to them?

G'Day All and Thanks in Advance. In all OS (particular Windows), when a file is deleted, I am under the impression that the file is marked as deleted but not removed from the PC just a flag is set for that file, (the file remains and can be recovered if required). If I move the file to a USB stick then delete that file is there any record of the file (left) on the PC. Thanks TopEnder

I'm running a live distro in ram. I need to write a password to a file. Later, I need to delete it securely.

I don't know how live file systems work, so I'm unsure if I open the file for writing, then write over it with data the length of the password, if it actually will write over that exact memory location or not.

I am not able to analyze the below code.. What I expected is that DELETED will be replaced with the first field in every line.But after giving a try, the output was different.

Can anyone pleas analyze and explain the code in detail? Many thanks...
