Actually the pipe is not causing the loop it's the poor design of bcrypts
key input. bcrypt doesn't check for end of input when reading the key in
and hence once it's read and rejected the first pair it will loop forever
processing nothing. There's no easy fix for this other then getting
someone to fix bcrypt, or use a different encryption program.
Your method for checking for an error is somewhat baroque as well. In
common with most programs bcrypt returns an exit status that indicates
and error so you could simply do:
if echo -e "${PASS1}\n${PASS1}" |bcrypt -r testfile 2> bcryptoutput.txt
then
echo all ok
else
echo error:
cat bcryptoutput.txt
fi
