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.

jrunscript

jrunscript(1)						      General Commands Manual						     jrunscript(1)

NAME

       jrunscript - command line script shell

SYNOPSIS

       jrunscript [ options ] [ arguments... ]

PARAMETERS

       options
	  Options, if used, should follow immediately after the command name.

       arguments
	  Arguments, if used, should follow immediately after options or command name.

DESCRIPTION

       jrunscript  is  a command line script shell. jrunscript supports both an interactive (read-eval-print) mode and a batch (-f option) mode of
       script execution. This is a scripting language independent shell. By default, JavaScript is the language used, but the  -l  option  can	be
       used  to  specify  a  different	language.  Through Java to scripting language communication, jrunscript supports "exploratory programming"
       style.

       NOTE: This tool is experimental and may not be available in future versions of the JDK.

OPTIONS

       -classpath path
	  Specify where to find the user's .class files that are accessed by the script.

       -cp path
	  This is a synonym for -classpath path

       -Dname=value
	  Set a Java system property.

       -Jflag
	  Pass flag directly to the Java virtual machine on which jrunscript is run.

       -l language
	  Use the specified scripting language. By default, JavaScript is used. Note that to use other scripting languages, you also need to spec-
	  ify the corresponding script engine's jar file using -cp or -classpath option.

       -e script
	  Evaluate the given script. This option can be used to run "one liner" scripts specified completely on the command line.

       -encoding encoding
	  Specify the character encoding used while reading script files.

       -f script-file
	  Evaluate the given script file (batch mode).

       -f -
	  Read and evaluate a script from standard input (interactive mode).

       -help
	  Output help message and exit.

       -?
	  Output help message and exit.

       -q
	  List all script engines available and exit.

ARGUMENTS

       If  [arguments...] are present and if no -e or -f option is used, then the first argument is the script file and the rest of the arguments,
       if any, are passed as script arguments. If [arguments..] and -e or -f option are used, then all [arguments..] are passed  as  script  argu-
       ments.  If [arguments..], -e and -f are missing, interactive mode is used. Script arguments are available to a script in an engine variable
       named "arguments" of type String array.

EXAMPLES

       Executing inline scripts

	  jrunscript -e "print('hello world')"
	  jrunscript -e "cat('http://java.sun.com')"

       Use specified language and evaluate given script file

	  jrunscript -l js -f test.js

       Interactive mode

	  jrunscript
	  js>print('hello world');
	  hello world
	  js>34 + 55
	  89
	  js> thread(function() { print('hello world'); }
	  hello world
	  js>

       Run script file with script arguments

	  jrunscript test.js arg1 arg2 arg3

       test.js is script file to execute and arg1, arg2 and arg3 are passed to script as script arguments. Script can access  these  using  "argu-
       ments" array.

SEE ALSO

       If JavaScript is used, then before evaluating any user defined script, jrunscript initializes certain built-in functions and objects. These
       JavaScript built-ins are documented in jsdocs.
