Subject: Re: Advise on best approach (truecrypt pw based on pdf
file)
Hi Demian
There should be space between grep and '^[A-Z]'. The ^[A-Z] regular
expression is for searching lines with a capital as first letter.
I've been thinking about rewriting this awk command to search a capital
letter other than 'I' at the end of string to break the inner loop.
Maybe I'll get rid of grep and change loop type.
Best Regards
