Unix Date Help

[ndoggy020]

Hey guys.

I need to manipulate the system date to move forward a day. So, if the system date was 02/14/08, I need the 'new' date to be 02/15/08 so my script will look for the date of 02/15/08. The thing is the file I will be looking for always has the date of the next day. Any simple unix command solution?

Any ideas,

Thanks

Here's a Perl solution if you can't find anything simpler. You'll need to download the Time::Piece and Time::Seconds modules from CPAN.

use warnings;
use strict;
use Time::Piece;
use Time::Seconds;
 
&init;
 
sub init
{
   my $today      = localtime();
   my $days_ahead = 1;
   my $date       = &get_days_ahead ( $today, $days_ahead );
 
   print "$date\n";
}
 
sub get_days_ahead
{
   my ( $date, $days ) = @_;
 
   for ( my $i = 0; $i < $days; $i++ )
   {
      $date += ONE_DAY;
   }
 
   return ( &get_mmddyy ( $date ) );
}
 
sub get_mmddyy
{
   my ( $date ) = @_;
   my ( $weekday, $month, $day, $time, $year ) = split ( / +/, uc ( $date ) );
 
   if    ( $month eq "JAN" ) { $month = "01"; }
   elsif ( $month eq "FEB" ) { $month = "02"; }
   elsif ( $month eq "MAR" ) { $month = "03"; }
   elsif ( $month eq "APR" ) { $month = "04"; }
   elsif ( $month eq "MAY" ) { $month = "05"; }
   elsif ( $month eq "JUN" ) { $month = "06"; }
   elsif ( $month eq "JUL" ) { $month = "07"; }
   elsif ( $month eq "AUG" ) { $month = "08"; }
   elsif ( $month eq "SEP" ) { $month = "09"; }
   elsif ( $month eq "OCT" ) { $month = "10"; }
   elsif ( $month eq "NOV" ) { $month = "11"; }
   elsif ( $month eq "DEC" ) { $month = "12"; }
 
   if ( length ( $day ) == 1 ) { $day = "0" . $day; }
   $year = substr ( $year, 2 );
 
   return ( "$month/$day/$year" );
}

if you have GNU date

# date +%Y/%m/%d -d "1 day"
