Hey u can use in simple version like this,

File.awk :
BEGIN {
FS=":"
}
FNR == NR { if (FNR==1) file1=FILENAME; arr[NR]=$0; next }
{
if ($0 != arr[FNR])
printf("%s\n", $0)
else
printf("%s\n",arr[FNR])
}

To run the above awk,

nawk -f File.awk << File 1 >> << File 2 >>

Redirect the above output to <<File 3>>

Then finally mv the File 3 to File 1.

DESCRIPTION

	Procedural style
       bool collator_sort_with_sort_keys (Collator  $coll, array  &$arr)

	Similar to collator_sort(3) but uses ICU sorting keys produced by ucol_getSortKey() to gain more speed on large arrays.

PARAMETERS

		-Collator object.

	      o $arr
		-Array of strings to sort

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

	      <?php
	      $arr  = array( 'Kopfe', 'Kypper', 'Kopfe' );
	      $coll = collator_create( 'sv' );

	      collator_sort_with_sort_keys( $coll, $arr );
	      var_export( $arr );
	      ?>

	      The above example will output:
