The ftprestart command provides an automated way to restart previously shutdown ftp servers. ftprestart is used when you are ready to re-enable your FTP server. It does the opposite of ftpshut and removes shutdown message files that were created by ftpshut. It will remove the system-wide shutdown message file as well as the shutdown message files in the anonymous ftp areas and any virtual ftp server areas.
The -V option causes the program to display copyright and version information, then terminate.
