In this article we are going to learn how to break file into many files to secure your data.
Sometimes we want our data to be secure even its hacked . Security agencies like FBI , RAW etc also use this technique to send information to someone or store them on their pc. They basically break important file into many files and store it on their system so if their system got hacked , the hacker won’t be able to take any information .
So let’s start . I’m gonna create a file to show you how to secure your file.If you already have a file thats ok you don’t have to create .I’m showing example with txt file but you can use any file like mp4, mp3 .pdf etc.
- First create a file by vim command.
[root@localhost S]# vim a.txt
- After entering vim command it will take you to the insert mode .
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ "a.txt" [New File]
- So type I and start writing what you want to write.

~ ~ ~ ~ ~
- hit esc button and type :wq (for save and quit)
~ ~ ~ :wq
- You can check your file is been created .
[root@localhost S]# ls a.txt
- Now we are going to break this file into 10 pieces .
[root@localhost S]# split -b 10 a.txt
- You can see your file is beeen broken into 10 different files . No one will be able read it .
[root@localhost S]# ls a.txt xaa xab xac xad xae xaf xag xah xai xaj xak xal xam xan xao xap xaq
- Now delete the file because its no longer needed . Because its been already in 10 different files .
[root@localhost S]# rm -rf a.txt
- Thats what you gonna see after deleting your file .Now no one will be able to see the content of the file not even you.You will also notice your 10 files having starting with letter X.
[root@localhost S]# ls xaa xab xac xad xae xaf xag xah xai xaj xak xal xam xan xao xap xaq
This is how you can break your file . And one more thing guys you can do this procedure with any file like .mp4 , .mp3 , .pdf , etc.
- Now how to get back your content of the file , by joining all 10 files .I’m going to combine all 10 file into one file .
[root@localhost S]# cat x* >deepit.txt
- Now try to open your new file that is been created .
[root@localhost S]# cat deepit.txt hiii im Deepit my site deepitp5.wordpress.com zodiac sagittarius loves music and to travel birthday 11 dec linux windows ccna cloud computing tricks android
So this how you can break your file and joint your file .
