Lets start
Chattr :- Chatter stands for the (change attributes) if we are apply the chattr then root and other users are not able to delete or modify the files .We are using the chattr to secure accidentally deletion of file or directory.

Chattr are two types
1 a
2 i

a :- when we are apply this chattr  we are able to append in the file but we are not able to delete ,modify,rename,copy on other location and when we are open the file in the editors the file is open read only.

i :- when this type of chattr aplly on the file or directory we are able to copy this file but can't append ,delete,modify,rename or move the file.

syntax :- chattr +a <file path>

in this chattr is command and +a is attribute .

2 How to remove chattr a on a file
