HowFlow — Little script which retrieve weather information on your console. Forget vista sidebar ;)

If you ever asked yourself if it possible to get the temperature outside without google or going to the window – here is a solution:

Simple look up which Airport ist next to you.

For example Nuremberg is EDDN.

Usage: weather stationID

Example:


weather EDDN

Retrieving information for EDDN:

date:  2008.04.28 1850 UTC
temp:  13 degree Celcius / 55 degree Fahrenheit

Put the code in your ~/.zshrc. It creates a new function with the name “weather”.

( You can also put this in /usr/local/bin/weather have a look at http://howflow.com/pastes/42 )


weather() {
    [[ -n "$1" ]] || {
        print 'Usage: weather <station_id>' >&2
        return 1
    }

    local PLACE="${1:u}" 
    local FILE="$HOME/.weather/$PLACE" 
    local LOG="$HOME/.weather/log" 

    [[ -d $HOME/.weather ]] || {
        print -n "Creating $HOME/.weather: " 
        mkdir $HOME/.weather
        print 'done'
    }

    print "Retrieving information for ${PLACE}:" 
    print
    wget -T 10 --no-verbose --output-file=$LOG --output-document=$FILE --timestamping http://weather.noaa.gov/pub/data/observations/metar/decoded/$PLACE.TXT

    if [[ $? -eq 0 ]] ; then
        if [[ -n "$VERBOSE" ]] ; then
            cat $FILE
        else
            DATE=$(grep 'UTC' $FILE | sed 's#.* /##')
            TEMPERATURE=$(awk '/Temperature/ { print $4" degree Celcius / " $2" degree Fahrenheit" }' $FILE| tr -d '(')
            echo "date: $DATE" 
            echo "temp:  $TEMPERATURE" 
        fi
    else
        print "There was an error retrieving the weather information for $PLACE" >&2
    print "For example Nuremberg is EDDN" 
    print "more places: http://en.wikipedia.org/wiki/List_of_airports_by_ICAO_code:_E" 
        cat $LOG
    rm $HOME/.weather/$PLACE
        return 1
    fi
}
