Bug skipping echo stmnt first time a while loop entered
one more question. I want to skip the first echo statement the first time the loop gets entered

while [ $total_inserted -lt $selling_price ] #keep prompting for more funds until selling price achieved
do

echo "You have inserted a total of ${total_inserted} cents. Please insert $total_remaining more cents"
echo 'Please insert coins (NDQR)'
read coin_inserted

Otherwise the progam will tell user that he entered 0 cents, which is pointless. Any ideas???

DESCRIPTION

       Funding Free Software

       If you want to have more free software a few years from now, it makes sense for you to help encourage people to contribute funds for its
       development.  The most effective approach known is to encourage commercial redistributors to donate.

       Users of free software systems can boost the pace of development by encouraging for-a-fee distributors to donate part of their selling
       price to free software developers---the Free Software Foundation, and others.

       The way to convince distributors to do this is to demand it and expect it from them.  So when you compare distributors, judge them partly
       by how much they give to free software development.  Show distributors they must compete to be the one who gives the most.

       To make this approach work, you must insist on numbers that you can compare, such as, "We will donate ten dollars to the Frobnitz project
       for each disk sold."  Don't be satisfied with a vague promise, such as "A portion of the profits are donated," since it doesn't give a
       basis for comparison.

       Even a precise fraction "of the profits from this disk" is not very meaningful, since creative accounting and unrelated business decisions
       can greatly alter what fraction of the sales price counts as profit.  If the price you pay is $50, ten percent of the profit is probably
       less than a dollar; it might be a few cents, or nothing at all.

       Some redistributors do development work themselves.  This is useful too; but to keep everyone honest, you need to inquire how much they do,
       and what kind.  Some kinds of development make much more long-term difference than others.  For example, maintaining a separate version of
       a program contributes very little; maintaining the standard version of a program for the whole community contributes much.  Easy new ports
       contribute little, since someone else would surely do them; difficult ports such as adding a new CPU to the GNU Compiler Collection con-
       tribute more; major new features or packages contribute the most.

       By establishing the idea that supporting further development is "the proper thing to do" when distributing free software for a fee, we can
       assure a steady flow of resources into making more free software.
