Shell Programming and Scripting

hello gurus,

i want a perl/shell script which once invoked should convert a set of EPOCH timestamps to local time ( IST..i want) .

how does it work ,i have an idea on that..but writing a perl/shell script for it is not possible for me...so i need help for the same.

my exact requirement is like this:
i would get a file containing 'n' EPOCH numbers & my script should convert these numbers into local time (IST) ( o/p we get when we type "date" command on prompt) .

locale on my server is set to IST.

thanks & regards

What os do you have ?

On a linux machine with GNU date, this can be done.

Code:

date -d '1970-01-01 UTC 1140164951 seconds' +"%a %b %d %T %Z %Y"

Replace 1140164951 with your epoch format time.

Something like

Code:

while read epoch_date
do
echo $(date -d "1970-01-01 UTC $epoch_date seconds" +"%a %b %d %T %Z")
done < input.txt

Not tested. If it doesnt work, play around with the double quotes that surround +"%a %b %d %T %Z".

i know one command:

bash$ perl -e '$date = localtime(xxxxxxxxxx);print "$date\n";'
where xxxxxxxxxx is epoch timestamp.

it works ,i guess...
how do i put it in a script where my input is a text file containing a column of EPOCH numbers?

how do i get the o/p? can v have the o/p in a diffrent file ? if yes,how?
can v take the o/p in excel ?

i m blank on "perl" scripting.
