Reading text file and comparing the dates in Kshell

I have a text file in which holidays are listed as YYYYMMDD. Here is the sample data of the file.

20090911
20090912
20090913

I need to read this file and see if the current day is listed in this text file. If today and any of the rows in my text file match, I need to do further processing. I am not sure how to compare the current day with the data from my text file. The code below is not working well as it Prints “today is a holiday”. I know this piece of code is working

(if $(date "+%G%m%d") = ${line_by_line})

Can someone help me with this? Please see my code below.

Thanks.

Pramodini

#!/usr/bin/ksh
. ~/.profile

while read line_by_line

do

if $(date "+%G%m%d") = ${line_by_line}
then
print "Today is not a holiday"
else
print "Today is a holiday"
fi

done < holidays.txt

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 7/4 Indep.
