Help! Yet another check element in array Question

Greetings,

DISCLAIMER: My shell scripting is rusty so my question may be borderline stupid. You've been warned.

I need to create a script that a) lists the content of zip files in a directory and b) sends out an `exception` report. My ZIP files contain a control file (for load check). I want to abort the whole process if the control file is missing from the ZIP file.

Typically a zip file will have its contents looking like this:

Code:
file_1231232345.ctl
filea.txt
fileb.txt
filec.txt

Here what I wrote so far:
Code:
#!/bin/bash

#get today's date in YYYYMMDD formart 
DAY=`date +%Y%m%d`

#populate array of HDD zipped log(s) for today 
HDD_ZIP_Array=(`ls *${DAY}*.zip`)
HDD_ZIPlen=${#HDD_ZIP_Array[*]}

#echoes message if no files to process and exits. 
if [ $HDD_ZIPlen -eq 0 ]
then
        echo " HDD CheckZip -- $HDD_ZIPlen files! Process will exit!" ;         exit 1;
else
        for name in ${HDD_ZIP_Array[@]};
                 do
                echo " Zip File Name: $name"
                #list ZIP contents with unzip, remove header and trailer, 
                 #reverse sort to put control file name at index 0 and put file names in array().
                HDD_LIST_Array=(`unzip -l $name | head -n -2|tail -n +4 | sort -r | awk '{print $4}'`)
                HDD_LISTlen=${#HDD_LIST_Array[*]}
                #iterate array to 1) build exception report and 2) look for control file
                echo -e "Files in ZIP file: $name\n"     >> report.out
                        for (( i = 0 ; i < ${#HDD_LIST_Array[@]} ; i++ ))
                                do
                                        echo -e "${HDD_LIST_Array[$i]}"  >> report.out
                                done
                echo -e "\n  Number of files in ZIP file: $HDD_LISTlen."  >> report.out
              #since the name of the control contains a random number, glob CTL extension
               if [ $i != {*ctl} ]
              then
                   echo "Control file not found!" ; exit 2;
                fi
                done
fi

It is basic but it works. Except the bottom part where I test for the CTL file extension. It is not working whether the file is here or not.

What am missing?

Thanks for your input.

DH_INSTALLDEB(1)						     Debhelper							  DH_INSTALLDEB(1)

NAME
dh_installdeb - install files into the DEBIAN directory SYNOPSIS
dh_installdeb [debhelperoptions] DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with the correct permissions. FILES
package.postinst package.preinst package.postrm package.prerm These maintainer scripts are installed into the DEBIAN directory. Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands. package.triggers package.shlibs These control files are installed into the DEBIAN directory. package.conffiles This control file will be installed into the DEBIAN directory. In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this program, so there is no need to list them manually here. package.maintscript Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. Any shell metacharacters will be escaped, so arbitrary shell code cannot be inserted here. For example, a line such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert maintainer script snippets into all maintainer scripts sufficient to move that conffile. A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
