If I'm reading this correctly, your directories would look something like this.
Quote:
images_501:12_Date
images_502:13_Date
If this is true:
Try this:
Code:
#! /bin/ksh
# cd images
cnt=0
find ./ -name \*Date -type d | sed -e 's/_/ /g' -e 's/:/ /g'| awk '{print $2,$3}'| sort | while read line
do
  if [[ ! -z "$line" ]]
  then
    myarray[$cnt]="$line"
    cnt=$(($cnt+1))
  fi

  if [[ -z "$line" ]]
  then
    echo "No length"
  fi
done

ncnt=0
while [ $ncnt -lt $cnt ]
do
  echo "My Array: ${myarray[$ncnt]}"
  ncnt=$(($ncnt+1))
done

if not, AND they all begin with images then substitute the
Quote:
\*Date
with
Quote:
images\*
You really should have something to make sure you only get the directories you want and not the . and .. directories as well. They will show up as No Length.

Hope this helps

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--help] [--version] [bug-report-email-addresses]

DESCRIPTION

       bashbug is a utility for reporting bugs in Bash to the maintainers.

       bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor
       once you have completed the missing fields.  bashbug will notify you of any problems with the report and ask for confirmation before
       sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed
       by giving a comma separated list of bug-report-email-addresses.

       If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent.

OPTIONS

       --help
	      Show a brief usage message and exit.

       --version
	      Show the version of bashbug and exit.

       bug-report-email-addresses
	      Comma separated list of recipients' email addresses. By default the report is mailed to both the GNU developers and the Debian Bash
	      maintainers.

ENVIRONMENT

       DEFEDITOR
	      Editor to use for editing the bug report.

       EDITOR
	      Editor to use for editing the bug report (overridden by DEFEDITOR).
