Shell Programming and Scripting

Hi experts,

I am reading two log files and passing dates as output to a txt file.
Code is given below:

echo "Start Time:" >> Report.txt
cat start.log | while read LINE1
do
echo $DATE1 >> Report.txt
done
echo "End Time:" >> Report.txt
cat end.log | while read LINE2
do
echo $DATE2 >> Report.txt
done

The out put:
Start Time:
Tue, Feb 19, 2008 08:00:02 PM
End Time:
Wed, Feb 20, 2008 02:19:09 AM

Now I want to print the overall time difference between the first output (ie $LINE1) and second output (ie $LINE2)in day-hours-minutes-seconds format.

I read the FAQs on subtracting dates, but couldnt find a method to subtract two dates in the above format.

Thanks in advance.

you haven't found an answer here ?

I use HP -UX and date -d doesnt work

What about datecalc ?

hi vino,

Can you please help me in understanding how datecalc can be made usefull for this particular issue(to input date which is of the format day ,month date ,year , hours minutes seconds AM/PM)?

Did you manage to copy datecalc script to your machine ?
There is a self explainable documentation in that script.
Just type 'datecalc -help'.

Hi Mani,

I am having datecalc.sh in my system.
But its throwing me the following error while i try "Wed, Feb 20, 2008 02:19:09 AM" as in put.
"Wed: Not an editor command"

Please help me in understanding utilizing this script to input characters such as "Wed","Tue"

Thanks in advance,
Sree
