If you want to keep files, you can use the following logic:

Code:
# In this case it will look for directories from 30 until 50 (30 + 20) days ago!
countValBack=20
initVal=30
countValues=`expr ${initVal} + ${countValBack}`

basePath="./"

while [ ${countValues} -ge ${initVal} ]
do
	currDate=`date -d "${countValues} days ago" +"%Y%m%d"`
	bpDate="${basePath}/${currDate}"
	if [ -d "${bpDate}" ]
	then
		echo "Removing directory: [${bpDate}] - [${countValues}] days ago..."
		# rm -rf "${bpDate}"
		if [ ${?} -eq 0 ]
		then
			echo "Removed successffully!"
		else
			echo "Failed to remove."
		fi
	fi
	
	countValues=`expr ${countValues} - 1`
done

This in in this post!

A few changes will suit your needs!

I hope it helps.

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
