You did not inform us how you stored the oldprice in printfile. Assuming you stored it as a number i.e. 139.02 and not as $139.02, the following should work for you.

wget -qO- | awk -v oldprice=`cat pricefile` '
    /<b class="price">/ {
    newprice = substr($0,2) + 0.00

    if (oldprice == newprice) {
        print "The price is the same"
    } else {
        print "The price is not the same"

Finance::Quote::Trustnet(3pm)				User Contributed Perl Documentation			     Finance::Quote::Trustnet(3pm)

Finance::Quote::Trustnet - Obtain unit trust prices from SYNOPSIS
use Finance::Quote; $q = Finance::Quote->new; %stockinfo = $q->fetch("uk_unit_trusts","trust-name"); # Can failover to other methods %stockinfo = $q->fetch("trustnet","trust-name"); # Use this module only. DESCRIPTION
This module obtains information about UK unit trust prices from The information source "uk_unit_trusts" can be used if the source of prices is irrelevant, and "trustnet" if you specifically want to use UNIT TRUST NAMES
Unfortunately there is no unique identifier for unit trust names. Therefore enough of the name should be given including spaces to yield a unique match. Trustnet sometimes uses abbreviated names, and the string given should match the abbreviation. Consult to find a match for your unit trusts. Example "jupiter income" LABELS RETURNED
Information available from Trustnet may include the following labels: exchange method source name currency bid ask yield price. In case of a unit trust, "price" returns the offer (ask) price. In case of an OIEC, the unique price is returned in "bid", "ask" and "price". SEE ALSO
