How Can i use "--stdout" with masks ?

[monminamon]

Edit : tried redirecting the output it some times works and some times not
like for small masks like this it doesn't write to the text file at all it just creates an empty one

hashcat64.exe -a 3 ?h?h --stdout > ttt.txt

"also does the ?h not include the full alphabet? only abcdef ?"

tried the above mask and turns out yes : (

also it would be great if there is a way to make it show info about the wordlist before generating it
just like this
