Subject: Re: Advise on best approach (truecrypt pw based on pdf
file)
Hi Marek,
I tried Markov over night , but it doesn't look really good - I had
trained it on a pwd file generated from the pdf (with keeping only first
letters of each word), but it cretaed mostly candidates like
titttttttttttaief
So, I wanted to get back to the awk version and run it on a similar file
created from the pdfs in the relevant folder, alas, I get
cat all5 | awk '{for (i = 1; i <= length($1);
i++){for(j=i+4;j<i+12&&j<=length($1);j++){print substr($1, i,
j-i+1);}}}' | grep'^[A-Z]' > all6
grep^[A-Z]: command not found
I don't know enough about bash programming to sort this one out and
hence would come back to your advise, if you don't mind ...
Thanks,
Demian
