Using mail in awk
I'm having a bit of trouble using the mail command within awk. I'm sending the contents of the body through a pipe like so:
Code:
wget -qO- http://cs.actx.edu/~craddock/unix2/lab11 | awk -v oldprice=`cat pricefile` '
    /<b class="price">/ {
    print "The old price is: " oldprice
    getline
    retrievedprice = substr($0,2)
    print "The retrieved price is: " retrievedprice

    if (retrievedprice ~ oldprice) {
        print "The price is the same"
    }
    else{
        print "The price is not the same"
        print "Old price: $" oldprice "\n New price: $" retrievedprice | "mail -s "The Price Has Changed" username"
        print retrievedprice > "pricefile"
    }
}'

but when I attempt to run the shellscript, It does not appear to see the subject and assumes the username is the subject, so it asks for the recipients. Is it possible to use mail like this? When I use mail without a subject line it works fine.

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

NAME

       Finance::Quote::Trustnet - Obtain unit trust prices from trustnet.co.uk

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 www.trustnet.co.uk.  The information source "uk_unit_trusts" can be used if
       the source of prices is irrelevant, and "trustnet" if you specifically want to use trustnet.co.uk.

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 http://www.trustnet.co.uk/ut/funds/perf.asp?sort=0 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".
