What does running 'chmod 777' do?

• A. It restricts read-only access
• B. It removes all permissions
• C. It gives read write and execute permissions to the owner, group and others
• D. It sets permissions to execute only

Answer: (C)

chmod 777 sets the file’s permissions to rwxrwxrwx. In Unix-like systems, permissions are shown in three groups: owner, group, and others. Each group can have read, write, and execute; the digit 7 equals 4 (read) + 2 (write) + 1 (execute). So 7 7 7 gives full permissions to everyone: read, write, and execute for the owner, the group, and all other users. This means any user can view, modify, and run the file, which is why this is generally discouraged for sensitive files due to security risks. The other descriptions would imply more restrictive or different permissions (like read-only, no permissions, or execute-only), which don’t match what 777 actually does.
