Syntax and functionality of -start_from X

[puck2]

I am trying to restart from a percentage as mentioned in USAGE

-start_from Skip first N combinations ( you can specify N as percentage. F.e. : 30% )

When I enter

-start_from 24%

in my command, I get the following error:

invalid value "24%" for flag -start_from: strconv.ParseInt: parsing "24%": invalid syntax

What is the valid syntax?

Secondly, I have tried -start_from N but get no response. First run reports total possible combinations as 80,000,000. So I try ~24% of 80,000,000 and use

-start_from 19000000

And script just beings and never progresses... Maybe I'm not waiting long enough, but how is it calculating which is the Nth permutation and does starting at N actually save time or does it have to run through all the permutations to figure out what the Nth permutation is?

I was having a long waiting time too.
This is due to system first creates combinations of your template, and save them in memory I guess.
Then it starts checking passwords on by one.

I can suggest following to speed up things .

Instead of using combinations Create a password file it self, with all passwords combinations in it .

Say you saved them in pass.txt

and use them -l pass.txt to read them. Then you can skip records when you again resume.

Thanks
