Playing with Programs

Charles Weir and yours truly made a small script to combine multiple horoscopes into one (the exercises some people come up with….:)

We completed a minimal implementation – only for taurus (could easily be parameterized in the next bit). It consists of a shell script that downloads a horoscope from yahoo, and downloads one from astrology online. It’s two scripts, since we extracted the extraction code for astrology online to a script called …extract.pl.

rm -f taurus*
rm -f daily.htm*
wget http://www.astrology-online.com/daily.htm 2> wget1.out
./extract.pl daily.htm > first.txt

wget http://astrology.yahoo.com/astrology/general/dailyoverview/taurus 2> wget2.out
cat taurus | grep Quickie  | sed 's/<.*b>(.*).*>/1/' > second.txt

cat *.txt

extract.pl :

#!/usr/bin/perl -w

while ( <> )
{
if (/CHANGE TAURUS/)
{
$printing = 1;
next;
}
if (/END TAURUS/)
{
$printing = 0;
}
if ($printing)
{ print ;}

}
