# ls -l
You can obtain root permissions in Linux by using the "sudo" command before executing a command that requires elevated privileges. This allows you to temporarily act as the root user to perform administrative tasks. Alternatively, you can switch to the root user using the "su" command by entering the root user's password.
Create a file and set it's permissions to 222
An admin account allows for the user to have all the permissions to the computer and is known as the top level user. A user account has some permissions but not full access permissions to the OS that an admin would have. Based on greater permissions: 1. Admin 2. User 3. Guest
The permissions helps to restrict/monitor the movement(accessing of resources) of the user in the domain.
read, write, execute
In Linux the chmod command is used to set file permissions.
File permissions in Linux are not represented in binary format, but rather octal format. The first digit represents owner permissions, second digit is group permissions, and the final one is permissions for everyone. Read permissions are assigned a 4, write permissions are assigned a 2, and execute permissions are assigned a 1. A 6 permission allows read and write (4+2).
Yes, they have no effective permissions.
@Linux : for an example : for a file named " lastlog " Here are its permissions : -rw-r--r-- 1 root root 29492 Dec 1 15:12 lastlog Which means-- here( r )stands for -----Read (w)stands for -----Write and (x)stands for -----Execute Permissions respectively In Detail: User has rw- Permissions(read,write permissions and no execute permission) Group has r-- Permissions and Others have r-- Permissions for the file lastlog* . Extra info : root root ----Means that it is owned by root user(first root) and it belongs to group root (second root). Hope it helped.
User Group
For security purposes, accounts are given permission to do various tasks. If an account was not created by an administrator, it would have to either a.) have no permissions, and thus not be able to do anything, or b.) have a large number of permissions, possibly to do something an administrator wouldn't want them to do.
The last answer to this was incorrect. Whether or not you are the only user on the system or not: Linux is always a multi-user operating system.
