Can I just say, this is such a frustrating and yet enormously rewarding field of study. I'm in the middle of configuring GeekTool (Uh oh, stupid n00b) and I really only have one question.
I'm using Automator to grab a RSS feed, having GeekTool continually run that application every 10 minutes, putting the results in a text file and then displaying that .txt file. However, the RSS codes their dates by their standards and I don't know how to intercept that and change them to my own time zone.
Here's a picture:
Here's the GeekTool code that runs it:
head -n 300 ~/Documents/Notes/GeekTool/RSS/Cheatsheet.txt | tr '[\n]' '~' | sed 's/~~/\
/g' | sed 's/~//g' | sed 's/-0000//g'
----
Bonus question: Why is my script cutting off the text file at "NASA unveils ..."? There's plenty room in the window and the actual text file has more content than that. Is there a character limit cut-off that I'm missing in the code?
Thanks for reading!
Without seeing the data which produced that, we're only guessing.
Oh okay. What other information do you need? The automator script?
The code I copied and pasted above is what I put in the "Command" line of GeekTool. There isn't a separate Shell file beyond that.
Give us the original input and desired output

Okay. So basically I'm extracting from a xml feed and converting it to plain text on a locally stored file.
So the .xml is saved and converted to a plain text file
Now I use GeekTool and a Shell script to display that file on my desktop
head -n 300 ~/Documents/Notes/GeekTool/RSS/Cheatsheet.txt | tr '[\n]' '~' | sed 's/~~/\
/g' | sed 's/~//g' | sed 's/-0000//g'
----
Now my question is how do I take these dates that were pulled from the xml file:
and alter them using a Shell script to display my desired time?
My desired output would be the date converted to my time zone: Eastern Time Zone, (UTC05). So basically the same format "yyyy-mm-dd hh:mm:ss" (remove the +0000) but just converted to my time. Can shell script do that?
Something like this?
#!/bin/bash
while read line
do
from_date=$( echo $line | sed -n 's/.* - \([0-9]*-.*\) +0000/\1/gp' )
if [ ! -z "$from_date" ]
then
to_date=$( TZ=UTC date '+%F %k:%M:%S' -d "$from_date IST" )
line=$( echo $line | sed "s/$from_date +0000/$to_date/g" )
fi
echo $line
done < inputFile
root@bt:/tmp# cat inputFile

And please try to paste the code in test format!

Ahamed, I hope you're patient with me. I'm still learning so much. So I pasted in your code with my previous code to make this:
head -n 300 ~/Documents/Notes/GeekTool/RSS/Cheatsheet.txt | tr '[\n]' '~' | sed 's/~~/\
/g' sed 's/~//g' | sed 's/-0000//g'
#!/bin/bash
while read line
do
from_date=$( echo $line | sed -n 's/.* - \([0-9]*-.*\) +0000/\1/gp' )
if [ ! -z "$from_date" ]
then
to_date=$( TZ=UTC date '+%F %k:%M:%S' -d "$from_date IST" )
line=$( echo $line | sed "s/$from_date +0000/$to_date/g" )
fi
echo $line
done < inputFile
root@bt:/tmp# cat inputFile
NEW DOLPHIN SPECIES DISCOVERED - 2011-09-16 13:09:00 +0000
IN AUSTRALIAN BAY
root@bt:/tmp#
root@bt:/tmp# ./run
NEW DOLPHIN SPECIES DISCOVERED - 2011-09-16 7:39:00
IN AUSTRALIAN BAY
root@bt:/tmp#
Now nothing displays. Maybe that's a GeekTool thing. In fact, maybe I should put your code in a separate .sh file and run that file instead of pasting both segments of the full code right into GeekTool like how I'm currently doing it. What do you think?
You haven't told us how you're converting this XML to text, so it's STILL difficult to really get a grip on your input data. But I see you've shown what the URL for the XML data actually is, which lets me do this:
$ cat geektool.sh
#!/bin/bash
wget -q http://www.tdbimg.com/ext/rss/cheatsheet/rss_cheatsheet.xml -O - |
# Convert xml into text. Set TZ to our time offset.
awk -v TZ="$(date +%:z)" -v RS="<entry>" -v FS="\n" 'BEGIN {
# Convert [+-]HH:MM into an integer value in seconds
split(TZ, A, ":");
if(A[1] < 0) OFF=((A[1]*60) - A[2])*60;
else OFF=((A[1]*60) + A[2])*60;
}
NR>1{ # Fix those pesky embedded tags
gsub("<", "<", $0); gsub(">", ">", $0);
# Loop through each line, looking for the ones we want
for(N=1; N<=NF; N++)
{
if($N ~ /<(title|summary)/)
{ # Strip out tags
gsub(/ *<[^>]+>/, "", $N);
print $N
}
else if($N ~/<updated/)
{ # Strip out tags
gsub(/<[^>]+>/, "", $N);
# Convert from YYYY-MM-DD to YYYY MM DD etc.
gsub(/[-T:Z]/, " ", $N);
# Convert from UTC to local time
print strftime("%F %T", mktime($N)+OFF);
}
}
printf("\n");
}'
