To match your requirement, the 'date' command should be:
Code:
date +'%d%m%Y%H%M%S'

The %Y gives a 4-digit year.

Statements like "which is not working" tell us nothing. What went wrong?

Maybe your script should be something like:

Code:
#!/bin/sh
DDMMYYYYHHMMSS=`date +'%d%m%Y%H%M%S'` # Evaluate the date once only
cd /vol/best/srcfiles
for filename in "Payor" "customer" "vendor" Employee"
do
       if [ -f "${filename} ]
       then
              mv "${filename}" "${filename}.${DDMMYYYYHHMMSS}"
       fi
done


Btw. The date format YYYYMMDD etc. is much better than DDMMYYYY etc. in filenames because the files will come out in chronogical order in a default "ls" directory list.

pmdate

PMDATE(1)						      General Commands Manual							 PMDATE(1)

NAME

       pmdate - display an offset date

SYNOPSIS

       pmdate [ offset ... ] format

DESCRIPTION

       pmdate displays the current date and/or time, with an optional offset.

       An offset is specified with a leading sign (``+'' or ``-''), followed by an integer value, followed by one of the following ``scale'' spec-
       ifiers;

       S      seconds
       M      minutes
       H      hours
       d      days
       m      months
       y      years

       The output format follows the same rules as for date(1) and strftime(3).

       For example, the following will display the date a week ago as DDMMYYYY;
	       pmdate -7d %d%m%Y

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP.  On  each	installation,  the
       file  /etc/pcp.conf contains the local values for these variables.  The $PCP_CONF variable may be used to specify an alternative configura-
       tion file, as described in pcp.conf(5).

SEE ALSO

       date(1), strftime(3), pcp.conf(5) and pcp.env(5).
