I will try to rephrase as I have a feeling we might've had misunderstanding as I'm not native English speaker.
I'd like to put all the found keys in a txt file. What exactly should I write after -o? is it something like -o C:/BTC/vanitysearch/file.txt where I specify the path to that particular file?

Let's say it simple. If you do this:

Code:

vanitysearch -c -o results.txt 1Me

Then results.txt will get bigger and bigger, containing 3 lines for each found address. In my case the first 6 lines are:

Code:

PubAddress: 1meEixrnWYtQFXUkDxnP3ENxXCmEZJ1kE
Priv (WIF): p2pkh:L5dBcsL9Pgmx5pDk1ii7ykdQPx17XQZuhEpofKQFWn4K382jXCUB
Priv (HEX): 0xFAC64ACC2BEBB389756AB9AB34A885F9F2879D960323293A0F51DB12881EF4DA
PubAddress: 1metAmdcDmYj5F5sgDsDHUJVdv3VMbeUb
Priv (WIF): p2pkh:KytWuwVt4DDoPjwvsuKQb2BDdMApd7jtPiymw6eekWYsycvrMKcH
Priv (HEX): 0x4FA34D7759299FEBD5DBB8DC0E4AA89C7B0EE8AD77D560382F7FFE6B8F08CFF8

This is what you wanted to know? Clear now?
However, nobody stops you from making a test with a very simple vanity rule which will give you results in seconds.

my mistake, of course it was -o file.txt command. still nothing though

-snip-

What? no.. I might be wrong or misunderstand you but I get output with -o on windows and linux without elevated privileges..
if there is nothing special in that regard to his setup it should produce output..

That question if for shlomogold since I've quoted his reply Undecided

As for the "Run as Admin", I have successfully reproduced his issue by pasting and running VanitySearch from the system disk which requires Admin rights (Windows10).
If I run it outside the system disk, it always produces an output file even without admin privileges.
That's why I'm asking about his OS and where vanitysearch's directory is.

yes i know and i weight in bcause i also answered him and if you can reproduce the issue.. ok.. and then priv's could be the issue..
though i don't see why that should be neccesary and also i don't have that issue on windows 10 on system volume self compiled or prereleased..

What's your OS?
Is VanitySearch stored in a system disk or drive without elevated privileges?

If your OS is Windows, you need to start Command Prompt as administrator in order to create an output file.
If it was launched normally, it will just print the result and wont create an output file.

What? no.. I might be wrong or misunderstand you but I get output with -o on windows and linux without elevated privileges..

I rather suspect that the test setup did not find a result ?! try something very simple like 1AB as a prefix...
still no output?...

the command output also shows the number of results at the very end [Found 0] if this does show Found 1 or more and your output file is empty then maybe something to look at with the privileges

still having problem with txt file though, I set -i file.txt and it is still empty

-i is only the IN file it will not be changed. Use -o OUT file for putting potential results in a file instead of the command line output.

you need nvidia gpu
install cuda
run like .... Vanitysearch.exe -b -t 0 -gpu -gpuId 0 -g 544,512

more examples in several of the last topic pages...

already done, it helped.

-gpu didn't work, something about CUDA, -g Invalid grid size GPU ID argument

Bonjour Jean Luc,

after reading the description it is still not clear for me if you can do multiple addresses search at once, when you set certain prefix i.e. 1xxxxxx and then have all of them found filled in your list of addresses?
1xxxxx1, 1xxxxx2, 1xxxxx3, …, 1xxxxx99 and so on? I mean when it is done automatically and not manual each time after only one address had been found? figured out

~~Another question: can't specify path for my txt file. I put it in the same folder as vanitysearch.exe but none of two commands work, not o- outputfile:test.txt, nor o-output:C/desktop/Vanity/test.txt~~ resolved, did it wrong before

now the problem is with gpu
-gpu didn't work, something about CUDA, -g Invalid grid size GPU ID argument

Merci

in this tests i found interesting address 1111111111111111111114oLvT2
its shorter than typical P2PKH 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2
and is not random generated

This is very well known address with Public Key hash 0000000000000000000000000000000000000000.

"Items lost" refers to items found by the GPU that match the lookup table. It is not only link to the number of prefixes your search, but also to the number of threads.
When you have a lookup size of 65536, each GPU thread will return 6*1024 items.
With -g 88,128 and a lookup size of 64660, the number of items found by the GPU is (in average) 6*1024*88*128*64660/65536 = 68 280 960‬ and cannot exceed 6*1024*88*128*65536.
This has to be improved.

I have more items lost than prefixes
Search: 2367367 prefixes
Warning, 68214971 items lost
... and still found something in late

you could still use -m 64000000 or is your performance tanking ?

Restart or no restart, it wouldn't matter all that much anyway since generating millions of keys per second and finding a matching prefix (or postfix, or middle fix or whatever) is a probability.

He must be talking about the -i argument that specifies a text file with a list of prefixes.

If that's the case, bangbumbang is correct because
during my test, it didn't changed the queue once I've edited my text file while vanityseach is running.

Stop. Add. Start. It will then start finding from a random spot. I believe it randomizes the search after every few million, or at least that's what the original vanitygen did.

as far as i can see it is only loaded b4 the calculation and then not used again... so a restart would be required

Sorry if this has been asked already, but is it possible to update the search text file with new prefix options while the program is running, or will it require a restart? (is that part of the base key creation?)

OK I see, I have to work on that issue, in some configuration, the memory exchange between GPU and CPU is not very well adapted.

OK I'll add this.

Total is the total number of key checked.
Prob is the probability to found at least 1 prefrix after Total tries (so, where you are) according to the difficulty.
According also to key rate, the third field [99% in 00:00:00] estimate when you will reach the displayed probability of having at least 1 item found.

The difficulty calculation of case insensitive search is trickly and the program may give a bad approximation.

maybe the Prob and the third could go in there own line and extend the information a little bit like

GPU: GPU #0 GeForce RTX 2080 Ti (68x64 cores) Grid(544x512)
[Prob 0.000000000000000000000000000000000000000001%]
[50% in 0040 years 124 days 33 minutes 50 seconds]
[719.57 Mkey/s][GPU 719.57 Mkey/s][Total 2^40.88][Found 0]

where prob is the entire keyspace divided by number of addresses or prexifes currently used ?!?! that would be a good "indicator" i think
and the time to find something just a little more readable or something along that line..

at the moment
[Prob 0.0%][50% in 4.46424e+31y]
Prob always stays the same when searching for addresses and 4.xxx+31y is also not that informative.
