find -type not working on release 5.1?

[Herculano de Lima Einloft Neto]

     Hello,

        I'm getting something like this:

    ]$ find /etc -type d

    -t    invalid option
    -y   invalid option
    -p   invalid option
    -e   invalid option

     d   unknown file

       One other thing..
    
    ]$ ls x* 
 
  doesn't seem to work right either.. it's returning all the files..? g*
works though..

  Thanks in advance for any help.
