Securely delete files/folders in Ubuntu

In brief, you should NEVER trust your HDD before handing it over to someone else!

The solution to this would be either wipe the whole HDD or at least wipe the files/folders that you need to keep out of reach.

There are two quick ways to do this on Ubuntu; shred and wipe. I prefer wipe because it can accept folders as well.

The point is to fill the place of your data with random bits multiple times, as follows:

  1. sudo apt install wipe
  2. wipe -rq folder_name

r: for recursive

q: for quick mode, with only 4 iterations of random data.


Note: This process is very time-consuming, even in quick mode, depending on how large your data is, and how fast the HDD you are wiping is.
