The command "chattr -i" is used in Linux systems to change the attributes of a file or directory. Specifically, the attribute being changed is the "immutable" attribute, which makes a file or directory unable to be modified, deleted, or renamed.
The command structure is as follows: "chattr -i ${filename_or_directory}"
Here, ${filename_or_directory}
refers to the name of the file or directory you want to modify.
The option "-i" is used to set or remove the "immutable" attribute. When "-i" is used, it sets the attribute, making the file or directory immutable. This means that no modifications, deletions, or renames can be made to the specified file or directory. If the file or directory was already immutable, using "-i" will disable the attribute, allowing modifications to be made again.
It's important to note that the "chattr" command requires root privileges to be executed. So, you may need to use "sudo" or switch to the root user before running the command.
