Run following command to overwrite your current data with random data.You don't need to install dd command, all Linux distributions include this command already. But it is also used for securely wiping out the contents of a hard disk or partitions. It is used to copy contents of one partition or disk to another. This command is originally used for Disk Cloning. If you want to truncate and remove file after overwriting, use "shred -u" option shred -u filename dd If you want it to overwrite file more than this, simply specify the desired number with "shred -n" option. Shred by default overwrites file with random contents 25 times. Run following command to securely remove any partition using shred Replace partition name with your desired partition. Run following command to remove file using shred utility. Shred: /usr/bin/shred /usr/share/man/man1/shred.1.gz Shred is installed by default on all Linux distributions, if you want, you can find its installation path by running following command: whereis shred It keeps overwriting the files with randomly generated data patterns so in this way it becomes very hard to recover any data from them even if hackers or thief uses high level of data recovery tools/equipments. "shred" command destroys files/folder’s contents in a way that it is impossible to recover. This command provides secure memory cleaning, simly run smem command on the terminal. “ smem” is used to clean the contents of memory, its true that RAM contents are cleaned when system is rebooted or powered off, but some residual traces of data still remain in the memory. Replace the "/dev/sda5" part with your partition name. First of all find out your swap partition by running the following command: cat /proc/swapsĮxample output of above command is show below: cat /proc/swapsįrom here, you can see that swap is set to which partition, and then securely clean it by running the following command. Swap partition is used to store data for running programs. " sswap" command is used to securely wipe your swap partitions. In this way it ensures that there are no more recoverable files/folders on the partition.

" sfill" checks the specified partition/directories for space marked as free or available, and then uses its algorithm to fill it up with some random data. Run following command in the terminal to install it in ubuntu: sudo apt-get install secure-delete Once Secure-Delete has been installed on any Linux system, it provides following four commands: Secure-Delete is a set of tools for Linux operating system and they provide advanced techniques for permanent removal of files. The methods mentioned below remove data completely so it becomes very hard for recovery tools to find traces of the actual data and recover it. Let’s see how we can safely and completely remove files/folders from our Linux system. Data removed using this command can be recovered by special file recovery tools. Linux users utilizes the well know “ rm” command to remove data from their operating system, but “rm” command works in the conventional fashion. It means that data is still there somewhere on the disk, this method is insecure, as any smart computer hacker can use any good data recovery tool to easily recover your deleted data. Whenever we remove anything, the operating system deletes just the index of the particular data. But in most cases, you don't want your private data to be recovered easily. This is a good thing in the scenario when you have accidentally deleted your critical data.
Any computer user with normal level skill set knows that any data removed from computer system can be recovered later with little bit of efforts.
