Securely delete a file called /tmp/login.txt:

shred -u /tmp/login.txt

You can add a final overwrite with zeros to hide shredding:

shred -u -x /tmp/login.txt

 Where,

  • -u : Remove file after overwriting
  • -x : Add a zero to hide shredding
  • -n NUM : Overwrite NUM times instead of the default 25

 

Shred a multiple files

Let us say you have 100 subdirectories and just wanted to get rid of all files:

 find -t f . -exec shred -u '{}' \;

Run shred on entire partition

shred -n 30 -vz /dev/hdb2
