Chattr Command in Linux

In Linux, file attributes are meta-data properties that describe the file’s behavior. For example, an attribute can indicate whether a file is compressed or specify if the file can be deleted. Some attributes like immutability can be set or cleared, while others like encryption are read-only and can only be viewed. The support for certain attributes depends on the filesystem being used. This article explains how to use the chattr command to change file attributes on Linux file systems.
