Top Forums Shell Programming and Scripting Date One Week Ago From Given Date, Not From Current Date Post 302470292 by Lakris on Tuesday 9th of November 2010 04:50:00 PM

Hi,
another way is to use the fantastic date command, if perl isn't a requirement, and sh is ok.
Example:
Code:
date +%Y-%m-%d -d "2008-01-03 -7 days"

or in Your case,
Code:
back_time=$(date +%Y-%m-%d -d "2010-07-23 -7 days")

or with variable start date
Code:
start_date=2010-07-23
back_time=$(date +%Y-%m-%d -d "$start_date -7 days")

lots of options and very pedagogic!
Smilie

Best regards,
Lakris

SYNOPSIS
string px_date2string (resource $pxdoc, int $value, string $format) DESCRIPTION
Turns a date as it stored in the paradox file into human readable format. Paradox dates are the number of days since 1.1.0000. This func- tion is just for convenience. It can be easily replaced by some math and the calendar functions as demonstrated in the example below. PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). o $value - Value as stored in paradox database field of type PX_FIELD_DATE. o $format - String format similar to the format used by date(3). The placeholders support by this function is a subset of those supported by date(3) (Y, y, m, n, d, j, L). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Turn a paradox date into a human readable form <?php $px = px_new(); /* make up a date as it could be stored in */ /* a date field of a paradox db. */ /* 700000 days since 1.1.0000. */ $days = 700000; /* Use the calendar functions to print a */ /* human readable format of the date */ echo jdtogregorian($days+1721425)." "; /* px_date2string() outputs the same */ echo px_date2string($px, $days, "n/d/Y")." "; px_delete($px); ?> The above example will output: 7/15/1917 7/15/1917 SEE ALSO
