Leave off the | bc and see what you're actually feeding into bc. If your script prints anything, you'll have to redirect that to /dev/null so that it doesn't get fed into bc.

Yeah; anything that prints to stdout in that loop gets sent to bc, that stuff included. You have to redirect your script to /dev/null with > /dev/null after the program.

that will bring me back to the loooong list of standard_in errors I had before. it pretty much puts me back where I was without >/dev/null by the looks of it when I remove | bc to check again.

it seems the problem is
Code:
:~/oblig1$ bash oblig2.sh
(
0 )
/ 100

okay, apparently bc doesn't like newlines.

You're also not getting any of the output you wanted. Smilie You might have to make a version of your script which prints no output.

Instead of echo "stuff" do

printf " %s " "stuff" so you'll get one long output string separated by spaces instead of newlines.
