Java Give input to a perl script while execution
Hi,

I have a perl script which prints me the epoch value of a specific date and time given.Now I want to proceed to a next step ie i want to give the input at the time of execution.
I have to initialise the date and time values in the script before executing it.But now i want to give the date as input during executing the script so that the script prints me the epoch time of any date i give.
Can someone please suggest me in getting this. Smilie
My code looks as below:

Code:
#!/usr/bin/perl
use Time::Local ;
$sec=00;
$min=01;
$hours=00;
$day=1;
$month=0;
$year=110;
$Beg_time = (timelocal($sec,$min,$hours,$day,$month,$year) * 1000);
print "Epoch Beg Value: $Beg_time\n";


Thanks and regards,
Jyothi

Hello Jyoti,

you can do by either of the following ways:
Code:
$val=<STDIN>;
$val=<>;

You can also take in the whole date at once in some format
Code:
$sec=00;
$min=01;
$hours=00;
$day=1;
$month=0;
$year=110;

$date=<> ; ##input sec:min:hours:day:month:year and then split date

OR
Code:
my ($sec,$min,$hour,$day,$month,$year) = split(/:/,<>); ##take input and split in one go. 
##process the values

Give input to a perl script while execution
Hi Gaurav,

print "hour is $hour\n";

Thanks and Regards,

Hi Jyothi , <> is a kind of input reader . DO NOT use it twice here with $date=<> and the next line. Then you are entering the date twice and with -w switch you will be notified that main::date is getting used only once. So remove the line
$date=<> or comment it. I already specified an OR in the two statements.
So you statement would be like
Code:
my ($sec,$min,$hour,$day,$month,$year) = split(/:/,<>);
print "hour is $hour\n";

At the prompt you enter the date as ->44:23:05:22:08:09

Note the fields delimited by colons.
and you get the output.

Gaurav,
