Hacking like Mr. Robot
Mr. Robot is a TV show about a young programmer called "Elliot", working as a cyber-security engineer by day, and a vigilante hacker by night.
In season 1 Elliot was planning how to hack E-corp with his Fsociety team and the DarkArmy, wich the hack was done in season 2 and where the revolution has started by an operation called "Stage 2". But in season 3 Elliot start feeling guilty, and having some regrets for being involved in this attack after the DarkArmy burned all the E-corporation buildings and many people have died.
So Elliot start planing of how to undo the hack, but he have no access to the Internet.So Darlene Elliot's sister got the idea to make Elliot join a CTF(capture the flag) competition, so Elliot can win the competition and continue his plan by stoping "Stage 2".

After stopping "Stage 2" Elliot want to clear his tracks from the DarkArmy and as we can see Elliot used the "shred" command
As we all know a deleted file could be retrieved by forensics investigations, and since Elliot is a hacker he already know that and he want his tracks to be uncovered.So the purpose of the "Shred" command is to overwrite his files by some random data.
Elliot used this command:
shred -f -n 3 *
- shred" the overwriting tool"
- -f "forces the change of permissions to allow writing if necessary"
- -n 3 "overwrites three time"
- * "Shredding all files"
Let's try this command on our own linux machine.
After shredding if we open the file we obtain this result:
