Bug Formatting date
Hi all


Code:
Y=`date +'%Y'`
M=`date +'%m'`
D=`date +'%d'`
if [ $M -eq 01 -o $M -eq 03 -o $M -eq 05 -o $M -eq 07 -o $M -eq 08 -o $M -eq 10 -o $M -eq 12 ] && [ $D -eq 01 ];then
yesterday=$Y$M`expr $D + 30`
echo $yesterday
else
if [ $M -eq 04 -o $M -eq 06 -o $M -eq 09 -o $M -eq 11 ] && [ $D -eq 01 ]; then
yesterday=$Y$M`expr $D + 29`
echo $yesterday
else
if [ $M -eq 02 -a $D -eq 01 ]; then
yesterday=$Y$M`expr $D + 27`
echo $yesterday
else
yesterday=$Y$M`expr $D - 1`
echo $yesterday

px_date2string

PX_DATE2STRING(3)					     Library Functions Manual						 PX_DATE2STRING(3)

NAME

       PX_date2string -- Convert paradox date into formated string

SYNOPSIS

       #include <paradox.h>

       char * PX_date2string(pxdoc_t *pxdoc, long date, const char *format)

DESCRIPTION

       Creates	a  string  representation  of  a  paradox  date  as  specified	in  the  parameter format.  The date must be either retrieved with
       PX_get_data_long(3)  after  calling  PX_get_record(3)  or  by  simply  using  the  long	value  in  the	pxval_t  struct  as  returned	by
       PX_retrieve_record(3).  The function uses internally the PX_timestamp2string(3) function.  The format string may contain all chars as docu-
       mented with PX_timestamp2string(3), though only those concerning the date will produce resonable results.

RETURN VALUE

       Returns pointer to string on success and NULL on failure.

SEE ALSO

       PX_timestamp2string(3), PX_time2string(3)
