Forensic Analysis
Permanently delete files or hard disk
  • shred -n 3 -vz filename (-u)
note: random data for 3 pass ( -n 3), be verbose (-v) and write a final pass of zeros over the file after completing the random overwrite passes (z),
if you don't specify -n 3, it will overwrite 25 times by default.
In most cases, when you shredding a file, you would also use -u option to tell shred to truncate the delete the file after overwriting it.
