Perl help
Hi ,

I wrote perl script to add 18 days to current date,but its giving what i have expected .Any help it should be appereciated
Code:
 tictock()
 {
 perl -e '
 $increment = 86400;
 @months = qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec);
 @weekDays = qw(Sun Mon Tue Wed Thu Fri Sat Sun);
 ($second, $minute, $hour, $dayOfMonth, $month, $yearOffset, $dayOfWeek, $dayOfYear, $daylightSavings) = localtime();
 $year = 1900 + $yearOffset;

 for($i=0, $thisyear = $yearOffset; $thisyear==$yearOffset ; $i++)
  {
  printf ("%4d%02d%02d ",  $month/$dayOfMonth/$yearOffset);
  $incr=($increment * $i) + $now;
  ($sec,$min,$hour,$dayOfMonth,$month,$yearOffset,$dayOfWeek, $dayOfYear, $daylightSavings)=localtime($incr);
  $year += 1900;
   $mon += 1;

       }'
       }


set -A arr $(tictock )
let i=0
#while [[ $i -lt ${#arr[*]} ]]
while [[ $i -lt ${#arr[*]} ]]
do

There are numerious errors in your Perl code. Here is some Perl code which should do what you want
Code:
$now = time();

for ($i = 0; $i < 18; $i++)
{
    ($sec, $min, $hour, $dayOfMonth, $month, $year) = localtime($now + $incr);
    printf( "%2d/%02d/%04d ",  $month + 1, $dayOfMonth,  $year + 1900 );
    $incr += 86400;
}

couldnt understand the purpose.
hope this helps:

Code:
tictock()
 {
 perl -e '
 $increment = 86400;
 @months = qw(Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec);
 @weekDays = qw(Sun Mon Tue Wed Thu Fri Sat Sun);
$now=localtime();
 ($second, $minute, $hour, $dayOfMonth, $month, $yearOffset, $dayOfWeek, $dayOfYear, $daylightSavings) = localtime();
 $year = 1900 + $yearOffset;

 for($i=1, $thisyear = $yearOffset; $thisyear==$yearOffset, $i<=18 ; $i++)
  {
  printf ("%02d/%02d/%4d ",  $month+1,$dayOfMonth,$year);
  ($sec,$min,$hour,$dayOfMonth,$month,$yearOffset,$dayOfWeek, $dayOfYear, $daylightSavings)=localtime(time + ($increment
* $i))
  }'
}

set -A arr $(tictock )
let i=0
#while [[ $i -lt ${#arr[*]} ]]
while [[ $i -lt ${#arr[*]} ]]
do
 print ${arr[i]}
 i=$(( i + 1))
 done

You can't pass a human formatted date to localtime, it has to be the date in epoch seconds. You first must translate 7/16/2009 into epoch seconds, which you can do using the core module Time::Local or installing a date module that does it for you.

You didn't read the documentation very well.

Quote:
It is worth drawing particular attention to the expected ranges for the values provided. The value for the day of the month is the actual day (ie 1..31), while the month is the number of months since January (0..11). This is consistent with the values returned from localtime() and gmtime().
The months are numbered 0-11 not 1-12, so July is 6 instead of 7.
