chattr command in Linux with examples
The chattr command in Linux is a file system command which is used for changing the attributes of a file in a directory. The primary use of this command is to make several files unable to be altered by users other than the superuser. As we know, Linux is a multi-user operating system. There is a chance that a user can delete a file that is of great concern to another user, says the administrator. To avoid such kinds of scenarios, Linux provides ‘chattr‘. In short, ‘chattr’ can make a file immutable, undeletable, only dependable and many more!
