Date and Time

[tchatzi]

i just wrote this lines

#!/usr/bin/perl -w
use warnings;
my $dnow = `date`;
my $tnow = `time`;
print "$dnow, $tnow";

and i was waitting to get the date and the time when i run it, but the thing is that the program waits for me to press 'return' button two times and then it gives me the date and the time like this

The current date is: Fri 12/17/2004
Enter the new date: (mm-dd-yy) , The current time is: 9:02:45.20
Enter the new time:
C:\Documents and Settings\Pengo\My Documents\Perl Code>

what did i do wrong?

fauls alarm i got what was wrong,
in msdos to get you the time and the date without the prompt for entering a new one is '/T'
so it is
my $dnow = `date/T`;
my $tnow = `time/T`;

but why did the program waited for the 'enter' and for two times before it shows me the date, the time and the prompt?

As you said, on msdos, the command [tt]date[/tt] and [tt]time[/tt] without arguments let you change the date and time. Each of them expected you (so waited for you) to enter a new date or time and to press return to validate. No surprise then.

You'd be better off using perl's functions, as it makes things more cross-platform. To get a decent human-readable date/time printout, do this:

my $datetime = localtime time;

If you want to print that directly, you have to ensure it's evaluated in a scalar context, otherwise the output will be pretty unintelligable:

print scalar localtime time;
