Bharath,
Please check below code and try to run using

<scriptname> <filename>

Code:

filename=$1
filedate=`ls -lrt $filename| awk '{print $7}'`
filetimestamp=`ls -lrt $filename | awk '{print $8}' |awk -F ":" '{print $1 $2}'`
fileyear=`ls -lrt $filename | awk '{print $8}'`
filetime=`ls -lrt $filename | awk '{print $8}'`
filemonth=`ls -lrt $filename | awk '{print $6}'`
current_month=`date +%c | awk '{print $2}'`
current_year=`date +%c | awk '{print $5}'`
current_date=`date +%d`
prev_date=`expr $current_date - 1`
date_diff=`expr $current_date - $filedate`
current_time=`date +%H%M`
time_diff=`expr $current_time - $filetimestamp`
if [[ ${#fileyear} -eq 4 ]] ; then
if [ $fileyear -ne $current_year ]  ; then
echo "File is not of year $current_year"
exit
elif [ $filemonth != $current_month ] ; then
echo "File is of year $current_year but not $current_month month"
exit
fi
elif [ $filemonth != $current_month ] ; then
echo "File is of year $current_year but not $current_month month"
exit
fi
 
if [ $filedate -eq $prev_date ] || [ $filedate -eq $current_date ]; then
if [ $filedate -eq $current_date ]; then
echo "File was last updated on $filedate $filemonth $current_year at $filetime"
elif [ $filedate -eq $prev_date ] ; then
if [ $time_diff -le 0 ] ; then
echo "File was last updated on $filedate $filemonth $current_year at $filetime"
else
echo "File was updated on $filedate $filemonth $fileyear but before 24 hours from now"
fi
fi
else
echo "File was updated before $prev_date $current_month $current_year"
fi

Cheers

holidays(4)							   File Formats 						       holidays(4)

NAME

       holidays - prime/nonprime table for the accounting system

SYNOPSIS

       /etc/acct/holidays

DESCRIPTION

       The   /etc/acct/holidays file describes which hours are considered prime time and which days  are holidays.  Holidays and weekends are con-
       sidered non-prime time hours.  /etc/acct/holidays is used by the accounting system.

       All lines beginning with an "*" are comments.

       The  /etc/acct/holidays file consists of two sections.  The first non-comment line defines the current year and the start time of prime and
       non-prime time hours, in the form:

       current_year	 prime_start	  non_prime_start

       The remaining non-comment lines define the holidays in the  form:

       month/day     company_holiday

       Of these two fields, only the  month/day is actually used by  the accounting system programs.

       The  /etc/acct/holidays file must be updated each year.

EXAMPLES

       Example 1: Example of the /etc/acct/holidays file.

       The following is an example of the /etc/acct/holidays file:

       * Prime/Nonprime Table for the accounting system
       *
       * Curr	  Prime     Non-Prime
       * Year	  Start     Start
       *
	 1991	  0830	   1800
       *
       * only the first column (month/day) is significant.
       *
       * month/day    Company Holiday
       *
	 1/1	      New Years Day
	 5/30	      Memorial Day
