Re: [Hampshire] Bash pipe creates infinite loop - why?

Everything returns. Bash stores the return code of the last run
command in $?. 0 is win, not 0 is an error of somekind. I can't
remember now why this is the wrong way around (0 being false > 0 being
true).

Try for instance:

cp file_that_exists file_that_does_not
echo $?
cp just_one_argument
echo $?

As Bob said, the problem is that bcrypt is looping indefinately.

I'm still not clear on what you're trying to do, but if you're already
using bash to compare your two strings, why don't you use it to make
sure they're at least 8 characters long?
