I’ve been trying to get a script working that fetches weather-data and converts it into an .ics file. The script works so far put I’m stuck at the point where I need to add specific static data. A thorough search through the forum did not point me into the right direction.
#!/bin/bash
##### Begin
DATE=$(date +'%Y%d%m')
TIME=$(date +'%H:%M:%S')
TEMPFILE="$(mktemp temp.XXX)"
if [ $? -ne 0 ]; then
echo "$0: Can't create temp file, exiting..."
exit 1
fi
##### Fetching weather data
curl http://ical.wunderground.com/auto/ical/global/stations/48698.ics?units=metric | awk 'NR==1 || NR==5 || NR==6 || NR==10 || NR==17 || NR==18 || NR==22 || NR==24 || NR==135' > $TEMPFILE
##### Adding specific calendar data
##### Cleaning up
cat $TEMPFILE | tr -d "r" > $DATE.ics
rm $TEMPFILE
exit 0
The output is as expected a .ics file that can be imported into a calendar:
BEGIN:VCALENDAR
VERSION:2.0
CALSCALE:GREGORIAN
BEGIN:VEVENT
DTSTAMP:20130412T000000Z
DTSTART;VALUE=DATE:20130412
SUMMARY:Thunderstorm 32C / 26C
END:VEVENT
END:VCALENDAR
In addition to the above output, the following data set needs to be imported between lines 3 and 4:
BEGIN:VTIMEZONE
TZID:Asia/Singapore
BEGIN:DAYLIGHT
TZOFFSETFROM:+0700
DTSTART:19330101T000000
TZNAME:GMT+08:00
TZOFFSETTO:+0720
RDATE:19330101T000000
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:+0730
DTSTART:19820101T000000
TZNAME:GMT+08:00
TZOFFSETTO:+0800
RDATE:19820101T000000
END:STANDARD
END:VTIMEZONE
I’ve been playing around with the following string but did not manage to produce a result (example):
awk ‘NR==4{$0=”BEGIN:VTIMEZONE”}1′ $TEMPFILE
Any help is appreciated!
