thanks for the explanation, needed that, also what modification is needed to display the non duplicate files as well but after all duplicate ones are displayed?

The easiest way is to redirect the output of the command to a file, eg dup_files and use grep to get the other files:

Code:
grep -v -f dup_files file

I now have a list of duplicate files, but the issue is I need to eliminate only the ones that are same not the ones that are different but still have the same name.

For eg
if the files are
david/project1/symbiosys.pdf
tom/project1/symbiosys.pdf

if both are workng on same project the pdf's may be similar, but I need to be sure, maybe by md5 checksum or something that can be found out,
but if the file size differs i need to save both of them, in 2 different folders to prevent them from overwriting.

Any suggestions or help in regards to shellscript needed.

Not sure if this is what you want but you can use ls -l to check the file size of the files:

Code:
awk -F"/" 'a[$NF]{system("ls -l " a[$NF]);system("ls -l " $0);next}{a[$NF]=$0}' file
