HELP, need a mask example

[DanielG]

nope ,seen it and nothing

It literally says on https://hashcat.net/wiki/doku.php?id=mas...ck#example 

Built-in charsets

• ?l = abcdefghijklmnopqrstuvwxyz
  
• ?u = ABCDEFGHIJKLMNOPQRSTUVWXYZ
  
• ?d = 0123456789
  

and

The following command defines a full 7-bit ascii charset (aka “mixalpha-numeric-all-space”):

-1 ?l?d?s?u

You seriously can't combine that info into what you want?
