How do file permissions work?
On a Linux computer, access permissions for files and directories specify how the operating system should respond to access requests. The following three categories of access permissions exist:- Read: Only the user can see files that have read access. The letter “r” or number 4 denotes read permission.
- Write: Users have the ability to edit files that need write access. The letter “w” or the number 2 denotes write authorization.
- Execution: Users have access to executable-allowed directories as well as the ability to run executable-allowed files as programmes. The letter “x” or the number 1 designates an execution authorisation.
- User: A user is the file’s owner.
- Group: Every other user in that group (the group to whom the file belongs) is included here.
- World: This access level is for everyone else, or anyone who is not the user nor a member of the same group as them.
