combination of attack mode?

[miccee]

have you tried --stdout and piping it ?
e.g.
hashcat <parms> --stdout | hashcat <params>

most of the time i ask how to do something atom tells me just that and most of the times he's just right ^^

Cool thanks! 

Code:

hashcat64 -a 6 rockyou.txt ?d?d?d?d --stdout | hashcat64 -m 2500 example.hccap -r best64.rule

Something like this? When I did this, unfortunately it doesn't provide me with an estimation of end time. Is there a better way? Thanks!
