I was unable to find a better way to get ls to list by modified times and not include directories. I tried various solutions but the directories were always included.

I will try your suggestion for the if and reply thanks.

Code:
for i in `ls -pcr | grep -v [\/] `
do
                echo "PRE; $PREMID_DT_TM and Post; $POSTMID_DT_TM"
        if [ -e ${i} ]
        then
            echo "Processing file ${i}"      
            TEMP=$(echo "${i}" | sed -e "s/$PREMID_DT_TM/$POSTMID_DT_TM/")
          if [[ "${i}" != "${TEMP}" ]]
                    then
                   mv ${i} ${TEMP}
                    fi
        fi
done

it's saying the then is unexpected.

Also i think I tried testing for inequality first i just kept trying different examples on google trying to get it to work.

unsquashfs

UNSQUASHFS(1)						  uncompress squashfs filesystems					     UNSQUASHFS(1)

NAME

       mksquashfs - tool to uncompress squashfs filesystems

SYNOPSIS

       unsquashfs [OPTIONS] FILESYSTEM [directories or files to extract]

DESCRIPTION

       Squashfs  is  a	highly compressed read-only filesystem for Linux. It uses zlib compression to compress both files, inodes and directories.
       Inodes in the system are very small and all blocks are packed to minimize data overhead. Block sizes greater than 4K are supported up to  a
       maximum of 64K.

       Squashfs  is  intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in con-
       strained block device/memory systems (e.g. embedded systems) where low overhead is needed.

OPTIONS

       -v, -version
	   print version, licence and copyright information.

       -d PATHNAME, -dest PATHNAME
	   unsquash to PATHNAME, default "squashfs-root".

       -n, -no-progress
	   don't display the progress bar.

       -no, -no-xattrs
	   don't extract xattrs in file system.

       -x, -xattrs
	   extract xattrs in file system (default).

       -p NUMBER, -processors NUMBER
	   use NUMBER processors. By default will use number of processors available.

       -i, -info
	   print files as they are unsquashed.

       -li, -linfo
	   print files as they are unsquashed with file attributes (like ls -l output).

       -l, -ls
	   list filesystem, but don't unsquash.

       -ll, -lls
	   list filesystem with file attributes (like ls -l output), but don't unsquash.

       -f, -force
	   if file already exists then overwrite.

       -s, -stat
	   display filesystem superblock information.

       -e EXTRACT_FILE, -ef EXTRACT_FILE
	   list of directories or files to extract. One per line.

       -da SIZE, -data-queue SIZE
	   Set data queue to SIZE Mbytes. Default 256 Mbytes.

       -fr SIZE, -frag-queue SIZE
	   Set fragment queue to SIZE Mbytes. Default 256 Mbytes.

       -r, -regex
	   treat extract names as POSIX regular expressions rather than use the default shell wildcard expansion (globbing).

   Decompressors available
       gzip

       lzo

       xz
