This is a better way to do the command though, it looks nicer...

PHP код:

CMD:acmds(playerid, params[])
{
    if(!IsPlayerAdmin(playerid))
        return SendClientMessage(playerid, -1, "SERVER: Unknown command."); 
    SendClientMessage(playerid, COLOR, "Message");
    return 1;
} 


Remember to include the exclamation mark (!), that means IS NOT or DOES NOT, so it is saying "IF playerid IS NOT admin RETURN SendClientMessage..." else if a player is an admin it will send the commands.

It's a personal preference, both work equally as well.
