Linux permission attributes:
r (read) View file content
w (write) Modify file content
x (execute) Run a file (if it's an executable program & is combined
with the read attribute)
An example of Linux permissions:
rwxrwxrwx
The first 3 belong to the user or owner: Owner level rwx: Owner can read, write & execute the file
The second 3 belong to the group: Group-level rwx: only members of the group to which the file belongs can read, write, & execute the file
The last 3 belong to other or world: Other level rwx: All users can read, write and execute
To change file permissions using the CLI, you would use "chmod"
Permissions example: rwxrw-r--
The owner has read, write, execute
Groups have read, write
Other have read
