Which command is used to restart the Samba service on a Linux system?

The command used to restart the Samba service on a Linux system is "systemctl restart smb." This command is part of the systemd system and service manager, which has largely replaced the older init systems in many Linux distributions.

Using "systemctl restart smb" effectively stops the Samba service if it is running and then starts it again. This is necessary when configuration changes have been made or if the service is behaving unexpectedly. The syntax 'systemctl' indicates that you are interacting with the systemd service manager, and 'restart' is the specific action being requested.

This command allows for more robust and controlled service management compared to older methods, as it provides better logging and manages dependencies effectively. By using the 'restart' command, it ensures that any operations requiring the service are aware of the service's current state after the action is performed.

Other commands may not perform the equivalent action. For example, starting a service with 'systemctl start smb' would only initiate it without stopping it first, which might not suffice in cases where a complete restart is needed. Similarly, the 'service' command is commonly used in distributions that support SysVinit but may not have all the features or functionalities of systemd. The last option, 'restart
