Help with find and Replace using sed
I have to update a paramater (dateMemLimit) present in a file, with a date (YYYYMMDD) equal to 5 days before the sysdate. The parameter will be in the following format.
dateMemLimit = 20091201
Please note the blank spaces present between 'dateMemLimit' &'=' and between '=' & '20091201'. I have to update this parameter everyday by invoking a script in cron. I managed to get the date value (which is equal to 5 days before the sysdate), but I am not sure how to replace the existing date value with the new one, that too without disturbing the blank spaces present in-between. Please help me to handle this, using 'sed'

LEARN ABOUT PHP
px_date2string
PX_DATE2STRING(3) PX_DATE2STRING(3)
px_date2string - Converts a date into a string.
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
