No, the owner of a file does not always belong to the same group as the group owner. The file owner is typically the user who created the file, while the group owner can be any group that has been assigned to the file, which may or may not include the file owner. Permissions can be configured independently for users and groups, allowing for different access levels.
What else can I help you with?
In the nfts permissions to access a particular file the only person who can regain access to it is the?
Data Base Properties"Owner" of the file. The owner always has the ability to modify the permissions of a file or folder.
What is the command used to change the file access permission?
Linuxchmod: change permission bits (only the owner and root are allowed to do this)chown: change owner and group (only root is allowed to change owner, group may be changed by owner)chgrp: change group (only the owner and root are allowed to do this)
What is Chmod?
It changes the permissions of the file to rwxrwxrwx (AKA full access to owner, group, and everyone).
What is Chmod 755?
755 means read and execute access for everyone and also write access for the owner of the file. When you perform chmod 755 filename command you allow everyone to read and execute the file, owner is allowed to write to the file as well.
What are the differences between Windows and Linux access control lists?
In Windows, files have an owner (usually the creator), but not a group, to which they 'belong'. - and the owner isn't really important in determining access rights. Files either have an explicit list of people and groups or inherit it from a parent directory. These lists specify individual users and groups (in a list) who have access to the directory/file/subdirectories, and the specific rights granted to each item. In Unix/Linux, each file and directory belongs to a specific user AND group - for example, configuration files may belong to user root and a group set up for administrators (typically called 'wheel'). Instead of having a list of people who can/cannot access the file, you simply specify read, write and execute privileges for the owner and group the file belongs to, and then anyone else. In Windows, if you have a configuration file, the owner doesn't matter. Instead you set the ACL to include any Administrators you want to access the file, as well as any other users that may need to read it, including the program it configures. In Linux, you'd perhaps set the same configuration file to belong to the root user, and the group to which the configured program runs in, and everyone to no rights at all - so only root and the program can read it. Or you could set the owner to the user the program runs under and the group that the Administrators belong to, so the program can read it and so that Administrators et.al. can change the file, but keep everyone set to no rights to keep the configuration secure. They are two different ways of accomplishing security, each with their own configuration peculiarities and performance issues.
What does the CHMOD command do?
Changes the permissions of a file or folder to grant or deny the ability to read, write, and/or execute the file for the current owner, the current group, or for all users of the system.
What command can be used to take full access of a file?
To take full access of a file in a Unix-like operating system, you can use the chmod command. For example, chmod 777 filename grants read, write, and execute permissions to the owner, group, and others. Be cautious when using this command, as it allows anyone to modify or execute the file. Always consider the security implications of changing file permissions.
What permissions does Linux have on files and directories?
Each file and directory can be marked read-only, writable, and executable. Each file / directory will contain three sets of permissions that can be marked as such, namely the owner, other users in the owners group, and users not in the group.
List and define the three classes of subject in an access control system?
Owner: This may be the creator of a resource, such as a file. Group: In addition to the privileges assigned to an owner, a named group of users may also be the granted access rights. World: The latest amount of access is granted to users who are able to access the system but are not included in the categories owner and group of this resource.
Assume in your homedirectory, you have a file called "file.txt" Change the permissions of the file so the owner can read and write; the group can read; and everyone else doesn’t have any permissions with one command?
To change the permissions of a file called "File.txt" so that the owner can read and write, the group can read, and everyone else has no permissions, you can use the chmod command with the octal number 644 (equivalent to rw-r--r--): "chmod 644file.txt."
