the correct syntax to pipe maskprocessor | cudahashcat in linux?

[n_lona]

As I am very stupid I used

Code:

mp64.bin -q 3 -r 4 ?a?a?a?a?a?a?a?a?a?a [color=#ff6633]-o -[/color] | cudaHashcat64.bin -m 1800 admin.hash

to decrypt the admin router account. This way I occupy all the space of the hdd, where can I find and erase the "-o - generated file"? thx
