How Can i use "--stdout" with masks ?
i tried something like this but it prints the passwords to the screen not to a text file

hashcat64.exe -a 3 a?h?h?h?h?h?d?d --stdout test.txt

searching here on the forum 

all i could find is using it for rules and .dic files 

hc64 d.dic -rr.rule --stdout empty.txt empty.txt

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

thanks  : )
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
A quick view in the "--help" or here, will learn you that the mask "?h" is for hex-characters only.

Use the other built-in charsets, and you'll do fine.
