i changed the above line of code to read
Code:
lynx -dump "http://www.w3.weather.com/weather/print/$1"

that way i could type:
Code:
get_weather 90210

and get different areas :)

o yea...on a side note...did weather.com change anything, cause it just doesn't work anymore :)
might be my network configuration...but nothing else seems affected (and no...it's not the coding changes :P)

yeah, they were doing some funky java coding and broke the code earlier today. even direct access to the URL was toast from a browser. i was having the same problems, but it's been fixed for like the past 3hrs.

*note* make sure to include the sed portion of the script or you won't get the decent ascii output...

here's an update rev,

since you can't use exit's in your functions because it'll log you out, here's one that you can use to dynamically validate the ZIP and extract the forecast data.

Code:
forecast() {
_ZIP=$1

if   [ $# = 1 ];then
     printf "$_ZIP\n" | egrep '^[0-9][0-9][0-9][0-9][0-9]$' >>/dev/null
     if   [ $? = 0 ];then
          printf "Your 10 Day Weather Forecast as follows:\n";
          lynx -dump "http://www.weather.com/weather/print/$_ZIP" | sed -n '/%$/s/\[.*\]//p';
          printf "\n"
     elif [ $? = 1 ];then
          printf "Bad ZIP code!\n"
     fi
elif [ $# != 1 ];then
     printf "You need to supply a ZIP code!\n"
fi
}

here's a patch to set a default ZIP code to extract the 10-day forecast data if you don't specify via the shell...this is also posted on USALUG...

Code:
--- .forecast1  Tue Feb 01 00:00:00 2005
+++ .forecast2  Tue Feb 01 00:00:00 2005
@@ -11,6 +11,8 @@
           printf "Bad ZIP code!\n"
      fi
elif [ $# != 1 ];then
-     printf "You need to supply a ZIP code!\n"
+     printf "Your 10 Day Weather Forecast as follows:\n";
+     lynx -dump "http://www.weather.com/weather/print/${_ZIP:-XXXXX}" | sed -n '/%$/s/\[.*\]//p';
+     printf "\n"
fi
}


enjoy :D,

In shell script form, and tweaked a bit.
links worked better for me than lynx, and I know perl better than sed.

Code:
#!/bin/bash
DEFAULTZIP=02138

getforecast() {
        echo "Your 10 Day Weather Forecast as follows:"
        echo "Day, Weather, High/Low (F), Precip. %"
        links -dump "http://www.weather.com/weather/print/$1" | perl -ne '/\d %\s+$/ && s/DEG//g && print'
        echo ""
}

if   [ $# -eq 1 ]; then
        if (echo "$1" | egrep -q '^[0-9][0-9][0-9][0-9][0-9]$'); then
                getforecast $1
        fi 
else
        getforecast $DEFAULTZIP
fi

I've taken the weather bot, written by Dave Crouse and adapted by Jeo, and I have combined it with the ten day forecast, written by Daenyth, and the result is the following script. It could be further optimized. Note that it calls two different text Web browsers and two different sites. It works, though. Feel free to modify it and post your improvements to it.

Code:
# forecast
#desc Find current weather stats and forecast for your zip code
#desc Ex: weather 03301
# weather 1.1 -Crouse
# With Updates by Jeo
# Modified to run stand alone by Brian Masinick
# NOTE: This tool uses the elinks text web browser
# Example:  !weather 03301
# Usage: weather + zipcode

  zipcode=$1
  if [ -z "$zipcode" ]; then
    echo "Please provide a zip code (Ex: weather 03301)"
  else
  unset response
# Add a backslash (\) after -dump-width 300 if this line splits
# across two lines; Should be one distinct line:
###################################################################################################################################################
  WEATHER="$(elinks -dump -dump-width 300 "http://mobile.wunderground.com/cgi-bin/findweather/getForecast?query=${zipcode}" | grep -A16 Updated)"

  if [ -z "$WEATHER" ]; then
    response="No Results for $zipcode"
    echo "${response}"
  else
    response[1]="$(echo "$WEATHER" | grep -Eo 'Observed.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print "Weather: " $1}')"
    response[2]="$(echo "$WEATHER" | grep -Eo 'Updated.*' |sed s/\ *\|\ */\|/g |awk -F\| '{print $1}')"
    response[3]="$(echo "$WEATHER" | grep -Eo 'Temperature.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}' | sed s/DEG/\ /g )"
    response[4]="$(echo "$WEATHER" | grep -Eo 'Windchill.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}'| sed s/DEG/\ /g)"
    response[5]="$(echo "$WEATHER" | grep -Eo 'Wind .*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[6]="$(echo "$WEATHER" | grep -Eo 'Conditions.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[7]="$(echo "$WEATHER" | grep -Eo 'Humidity.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[8]="$(echo "$WEATHER" | grep -Eo 'Dew.Point.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}'| sed s/DEG/\ /g)"
    response[9]="$(echo "$WEATHER" | grep -Eo 'Pressure.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"

    for index in `seq 1 9`; do
      if [ -n "${response[$index]}" ]; then
        echo "${response[$index]}"
      fi
      let "index = $index + 1"
    done
  fi
  fi

# This part was originally written by Daenyth

DEFAULTZIP=03301

getforecast() {
        echo "Your 10 Day Weather Forecast as follows:"
        echo "Day, Weather, High/Low (F), Precip. %"
        links -dump "http://www.weather.com/weather/print/$1" | perl -ne '/\d %\s+$/ && s/DEG//g && print'
        echo ""
}

if   [ $# -eq 1 ]; then

I had inadvertently omitted Daenyth in citing the original authors of the script that I pieced together.

Here is a version with updated documentation with the proper credit given. My apologies to Daenyth
for failing to cite his work in my original script.

Code:
#!/bin/bash
# forecast
#desc Find current weather stats and forecast for your zip code
#desc Ex: forecast 03301
# weather 1.1 -Crouse
# With Updates by Jeo
# Modified to run stand alone by Brian Masinick,
# and also added the forecast logic contributed by Daenyth.
# NOTE: This tool uses the links text web browser
# Example:  forecast 03301
# Usage: forecast zipcode

  zipcode=$1
  if [ -z "$zipcode" ]; then
    echo "Please provide a zip code (Ex: weather 03301)"
  else
  unset response
#  Should be one distinct line (using repeated slashes to help):
###################################################################################################################################################
  WEATHER="$(elinks -dump -dump-width 300 "http://mobile.wunderground.com/cgi-bin/findweather/getForecast?query=${zipcode}" | grep -A16 Updated)"

  if [ -z "$WEATHER" ]; then
    response="No Results for $zipcode"
    echo "${response}"
  else
    response[1]="$(echo "$WEATHER" | grep -Eo 'Observed.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print "Weather: " $1}')"
    response[2]="$(echo "$WEATHER" | grep -Eo 'Updated.*' |sed s/\ *\|\ */\|/g |awk -F\| '{print $1}')"
    response[3]="$(echo "$WEATHER" | grep -Eo 'Temperature.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}' | sed s/DEG/\ /g )"
    response[4]="$(echo "$WEATHER" | grep -Eo 'Windchill.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}'| sed s/DEG/\ /g)"
    response[5]="$(echo "$WEATHER" | grep -Eo 'Wind .*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[6]="$(echo "$WEATHER" | grep -Eo 'Conditions.*' | sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[7]="$(echo "$WEATHER" | grep -Eo 'Humidity.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"
    response[8]="$(echo "$WEATHER" | grep -Eo 'Dew.Point.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}'| sed s/DEG/\ /g)"
    response[9]="$(echo "$WEATHER" | grep -Eo 'Pressure.*' |sed s/\ *\|\ */\|/g | awk -F\| '{print $1 ": " $2}')"

    for index in `seq 1 9`; do
      if [ -n "${response[$index]}" ]; then
        echo "${response[$index]}"
      fi
      let "index = $index + 1"
    done

  fi

getforecast() {
