Is it possible to write a shell script to extract the number of files

in a particular directory in a specific time duration (lets say last 2 hours) and then dtermine how many combinations have the same file size and based on that, do a file compare for the extracted files having same file size.

You could write a simple shell script, or use perl. Look at curl and diff. I am not sure what comparing by file sizes will give you. Would'nt you rather do a md5sum check?

Something like this: # compare file checksums

md5new=`md5 -q $NEW_FILE` md5old=`md5 -q $LIST_FILE`

if [ $md5old = $md5new ] then # files are same, exit exit 0 fi

# files differ, mv new to old text list file mv -f $NEW_FILE $LIST_FILE
