brute-forcing not working with me

[seco]

the file contains only one hash only !! and the format is correct
i try to rename the file name to be one word but !! still the same !!

Code:

cudaHashcat-plus32.exe --attack-mode 3 --gpu-accel 8--gpu-loops 256--gpu-watchdog 90 --segment-size 32 "test.txt"

and the other one

Code:

cudaHashcat-plus32.exe --attack-mode 3 --gpu-accel 8--gpu-loops 256--gpu-watchdog 90 --segment-size 32 34d7d0165d1fe0934e2cb0ae952e0355

none of the above works with me but the following

Code:

cudaHashcat-plus32.exe -a=3 --custom-charset1 ?u --custom-charset2 ?l --gpu-accel 8 --gpu-loops 256 --gpu-watchdog 90 --segment-size 32 "test.txt"

started and says

Starting attack in wordlist stdin mode...
and begins
is that means that the attack started brute force attach with upper and lower charctersets ?
thanks
