okay, apparently bc doesn't like newlines.
You're also not getting any of the output you wanted.
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.

safe_finger
SAFE_FINGER(8) Linux Programmer's Manual SAFE_FINGER(8) NAME
safe_finger - finger client wrapper that protects against nasty stuff from finger servers SYNOPSIS
safe_finger [finger_options] DESCRIPTION
The safe_finger command protects against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges. It also runs the finger client with a defined PATH environment. safe_finger will also protect you from problems caused by the output of some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere on a line. File systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines. The finger server may take forever because it is somehow wedged. safe_finger takes care of all this badness. SEE ALSO
