# check the probability of rain.

# Bom URL http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDN10035.txt

wget -q -O - http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDN10035.txt | \ 
grep ^Probability\ of\ rain


Example ("$" is the prompt):

  • This is hardly "overprogramming". Just two commands, wget piped into grep. And yes, the first command, wget, does check the Australian Bureau of Meteorology page. The second command, grep, extracts out the line I am interested in. So just typing "rain" beats opening the browser, clicking some bookmark, and looking for that line.
