Re: How to get a date after a specific number of days?
Thank you all for your replies.
Is there any other specific command to do that?

Don't miss the run-time dependencies required as well.
With GNU date installed you can run:
date --d "+25 days" +%m%d%y
You'll need to put the path to the GNU date command in front of that, otherwise it will just invoke the HP-UX date command.
No doubt the perl-mongers on the forums will also be able to give you a perl one-liner for this as well.

Re: How to get a date after a specific number of days?
This might help you. Try this.
Result=$(perl -MPOSIX -le 'print strftime "%d%b",localtime(time+(60*60*24*25))')

Re: How to get a date after a specific number of days?
You might note that by using Perl and the 'strftime' function you can choose any date format you want. The format directives are equivalent to those you are familiar with in the 'date' command. Of course, see too the manpages for 'strftime(3C)'. For example:
# perl -MPOSIX -le 'print strftime "%d %b",localtime(time+(60*60*24*25))'
14 Mar
# perl -MPOSIX -le 'print strftime "%m/%d/%Y",localtime(time+(60*60*24*25))'
03/14/2011
# perl -MPOSIX -le 'print strftime "%m/%d/%Y %H:%M",localtime(time+(60*60*24*25))'

Re: How to get a date after a specific number of days?
That perl scripting really worked. Thanks a lot:)
But I am able to find the date after 25 days from today's date. Is there anyother modification I can do so that the perl will take my input?
Actually I need to find the date after 25 days from a specific date but not from today's date.Kindly help.

> Actually I need to find the date after 25 days from a specific date but not from today's date.
You can begin with something like this an embellish as you like. Notice that I require the input as YYYYMMDD.
# cat ./fromwhen
#!/usr/bin/perl
use strict;
use warnings;
use POSIX qw(strftime);
use Time::Local;
my $date = shift or die "Date (YYYYMMDD) expected\n";
die "YYYMMDD expected\n" unless
my ( $yyyy, $mm, $dd ) = ( $date =~ /(\d{4})(\d\d)(\d\d)/ );
my $when = shift or die "Number of days in future expected\n";
my $secs = timelocal(0, 0, 0, $dd, $mm-1,$yyyy );
print strftime "%Y/%m/%d\n",localtime($secs+(60*60*24*$when));
1;
...run as (for example):
# .l/fromwhen 20110218 13
2011/03/03
...which yields the date thirteen (13) days from February 18, 2011.
Regards!
