unix find latest version of file in subdirectories

i have to find the latest version of a file in subdirectories

user1@host1:/tmp/pathtofind> find . -name "*.txt" -printf "%T+ %p\n"
2013-11-21+13:34:05.7255244000 ./20131119/abc.txt
2013-11-21+13:33:56.5965250740 ./20131120/abc.txt
2013-11-21+13:34:17.6735259520 ./20131118/abc.txt
2013-11-21+13:33:53.0055261810 ./20131121/abc.txt

All I need is the path and filename of the latest version of the file for further processing, in this case it would be ./20131118/abc.txt

Can you please help me how to do this?

Regards, vishal

EDIT:

Sorry what I actually need is the last version of every distinct filename (abc.txt and def.txt) in a directory:

user1@host1:/tmp/pathtofind$ find . -name "*.txt" -printf "%T+ %p\n"
2013-11-21+17:56:48.4251785260 ./20131121/abc.txt
2013-11-21+17:56:57.8651782010 ./20131121/def.txt
2013-11-21+17:56:37.6731789030 ./20131118/abc.txt
2013-11-21+17:57:14.2571776330 ./20131118/def.txt
2013-11-21+17:56:24.2011793670 ./20131119/abc.txt
2013-11-21+17:57:24.4011772720 ./20131119/def.txt
2013-11-21+17:56:29.1371791980 ./20131120/abc.txt
2013-11-21+17:57:19.6411774490 ./20131120/def.txt

user1@host1:/tmp/pathtofind$ find . -name "*.txt" -printf "%T+ %p\n" | sort | tail -1
2013-11-21+17:57:24.4011772720 ./20131119/def.txt

only finds the latest version of a textfile.

what i actually need in this case would be:

2013-11-21+17:56:48.4251785260 ./20131121/abc.txt
2013-11-21+17:57:24.4011772720 ./20131119/def.txt

Pipe the above output to

sort -k1.43 -k1r|uniq -s42

- this sorts by filename (which starts at column 43) and then reverse by timestamp (so that the latest version comes first) and prints the first occurrence of each filename.

Change the printf format to emit the seconds since epoch and sort. Saying:

find . -name "*.txt" -printf "%T@ %p\n" | sort | tail -1

would print the newest file.

   -printf format
          ...
                 @      seconds  since Jan. 1, 1970, 00:00 GMT, with frac‐
                        tional part.
