PSCONFIG configdb parameters

I don't know if anyone else has experienced this, but the Microsoft documentation provides this as an example for the above command
Psconfig
–cmd configdb –create
–server servername
–database databasename
–user username
–password userpassword
–admincontentdatabase databasenameI tried running this and kept getting the following error
The -create command is invalidThis drove me made until I removed the "-" from the beginning of the create parameter and then I got the following error
The -server command is invalidMy amazing mind realised that a pattern was emerging and I went ahead and removed all the dashes from the parameters to end up with the following command.
Psconfig –cmd configdb create server servername database databasename user username password userpassword admincontentdatabase databasenameHey Presto my "SharePoint Products and Technologies Configuration Wizard" began chugging away
