Parse find input into array
I need help parsing the output of find into an array. I need to search 3 directories and find all files older than 31 days old. This is what I have so far.

Code:
TIME=" -maxdepth 1 -mtime +31"
DIR1="/dir1/"
DIR2="/dir2/"
DIR3="/dir3/"

FIND_DIR1=$(find ${DIR1}${TIME})
FIND_DIR3=$(find ${DIR2}${TIME})
FIND_DIR3=$(find ${DIR3}${TIME})

IFS=' ' read -a array <<< "$FIND_DIR1"
for element in "${array[@]}"
do
    echo "$element"
done

When I echo the FIND_DIR variables, it prints out..
/dir1/file1 /dir1/file2 separated by what I'm assuming is either white space or a tab.

The issue I'm having is when I try to put the output of the find into an array, array index 0 has both /dir1/file1and/dir1/file2

I need array index 0 to be file 1 and array index 1 to be file 2.

The above code will output /dir1/file1 for both array index 0 and array[@], it prints nothing when asked to print array index 1.

Thank you in advance.

meld

MELD(1) 						      General Commands Manual							   MELD(1)

NAME

       meld - Visual diff and merge tool for the GNOME Desktop

SYNOPSIS

       meld [options]
       meld [options] FILE1
       meld [options] DIR1
       meld [options] FILE1 FILE2 [FILE3]
       meld [options] DIR1 DIR2 [DIR3]

DESCRIPTION

       Meld  is  a  graphical diff viewer and merge application for the Gnome desktop.	It supports 2 and 3-file diffs, recursive directory diffs,
       diffing of directories under version control (Arch, Bazaar, Codeville, CVS, Darcs, Git, Mercurial, Monotone, RCS), as well as  the  ability
       to manually and automatically merge file differences.

OPTIONS

       --auto-compare, -a
	      Automatically compare all differing files on startup.

       --diff FILE1|DIR1 FILE2|DIR2 [FILE3|DIR3]
	      Create a diff tab for the given files or directories.  Note that "meld --diff FILE1 FILE2" is functionally equivalent to "meld FILE1
	      FILE2".  However, the --diff argument can be given multiple times for one invocation of meld which allows the user to  automatically
	      initiate multiple diffs when meld starts.  See examples below.

       --help, -h
	      Print application help and usage.

       --LABEL=<label>, -L <label>
	      Set application window title to <label>.

       --version
	      Print application version and exit.

EXAMPLES

       meld
	      Run meld without initiating a diff.

       meld FILE1
	      Initiate a diff between FILE1 and the version-controlled copy of FILE1.

       meld DIR1
	      Initiate a recursive diff between DIR1 and the version-controlled copy of DIR1.

       meld FILE1 FILE2
	      Initiate a diff between FILE1 and FILE2.

       meld FILE1 FILE2 FILE3
	      Initiate a 3-way diff between FILE1, FILE2, and FILE3.

       meld DIR1 DIR2
	      Initiate a recursive diff between directory DIR1 and DIR2.

       meld DIR1 DIR2 DIR3
	      Initiate a recursive 3-way diff between directory DIR1, DIR2, and DIR3.

       meld --diff FILE1 FILE2 --diff FILE3 FILE4
	      Initiate a diff between FILE1 and FILE2, and a separate diff between FILE3 and FILE4.
