What command is used to display the Samba server configuration options?

The command used to display the Samba server configuration options is testparm. This utility reads the Samba configuration file, typically located at /etc/samba/smb.conf, and checks its syntax while also displaying the current settings and options defined in the configuration. This is particularly useful for verifying configurations before starting or restarting the Samba service, as it highlights any potential errors or misconfigurations.

Using testparm allows system administrators to ensure that their Samba shares and settings are correctly set up and provides an easy way to review the active configuration parameters. This can help in debugging issues or confirming that the configuration is as intended, making it an essential tool for managing Samba in a mixed environment.
