The reason is very simple why you had all these chaos !!

The regex you used is greedy !! So make it non greedy and check.

Code:
for file in $(find /home/sathiya/t1/ -type f -name "*.pdf")
do
  echo $file 
  newfile="$(echo $file | sed 's/\(.*\)\(.*?\)_\(.*?\)_\(.*?\).pdf$/\4\3_\2_\1.pdf/')"
  echo $newfile
done

Tested, works as expected !

Let us know whether it helps. Also it is the solution for the previous problem you are facing, it will not move all the files to the script where the find is placed, it will rename all the files in the appropriate directories itself as with your mv command.

/home/smriti/Aquino_2008/Important_script_final_dec2008/rearrange_pdf_names/folder2/folder3/Bolsch-fing_TMDLL_2007.pdf
/home/smriti/Aquino_2008/Important_script_final_dec2008/rearrange_pdf_names/folder2/Tandge-Gh-lol_AMDLIKO_2008.pdf
/home/smriti/Aquino_2008/Important_script_final_dec2008/rearrange_pdf_names/folder2/Tandge-Gh-lol_AMDLIKO_2008.pdf

The above is the output, which means the files are not being renamed, was facing same issue earlier, when I sorted this the mv copied files at one location, not in directories.
So help required, and thanks for the response!

Below is the script i ran, did not put the mv command since file and newfile are same files.
Code:
for file in $(find /home/smriti/Aquino_2008/Important_script_final_dec2008/rearrange_pdf_names/ -type f -name "*.pdf")
do
  echo $file 
  newfile="$(echo $file | sed 's/\(.*\)\(.*?\)_\(.*?\)_\(.*?\).pdf$/\4\3_\2_\1.pdf/')"
  echo $newfile
done

Hopefully this worked ....

Code:
for file in $(find /home/smriti/Aquino_2008/Important_script_final_dec2008/rearrange_pdf_names/ -type f -name "*.pdf")
do
  echo $file
    newfile="$(echo $file | sed 's/\(.*\)\/\(.*\)_\(.*\)_\(.*\).pdf$/\1\/\4_\3_\2.pdf/')"
  echo $newfile
done

Does it works for you also, as you expected ?!?!

its woking, will try on more files and let ypu know, thanks!!!!

The script is working, but I wanted to know since i want to rename the file from NAME_DAME_2008, is there any way I can restrict the script to change files only ending with a year.
Example.
If the name of a file is Benzene_AMBL_pod.pdf
The script should not work
but if name is Benzene_AMBL_2008.pdf
the output should be 2008_AMBL_Benzene.pdf

thanks
