The ftpshut command is used to shut down the FTP server at a specified time. This command is useful for system administrators who want to schedule regular maintenance or shutdowns of their FTP server.
Overview
The ftpshut command takes a single argument, which is the time at which the FTP server should be shut down. This time can be specified using the following format: HH:MM, where HH is the hour (in 24-hour format) and MM is the minute.
For example, to shut down the FTP server at 11:30 PM, you would use the following command:
ftpshut 23:30
Once the ftpshut command is executed, it will wait until the specified time and then shut down the FTP server. Any users currently connected to the server will be disconnected.

The following table lists all available options for the ftpshut command:
| Option | Description |
