What is Linux attribute?

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.

How do I see file attributes in Linux?

You can list the attribute of the contents of a particular directory with lsattr command followed with a file or directory name as the argument. As the ls -l command, the -d option with lsattr will list the attributes of the directory itself instead of the files in that directory.
