Delete duplicate files from one of two directory structures
Hello everyone,

I have been struggling to clean up a back-up mess I created when manually duplicating a directory structure and then working in both of them..
The structures now are significantly different and contain in the order of 15 k files of which most are duplicates.
Now I am trying to merge those dirs and had a look at FSlint, Meld, diff, and fdupes.
While all of those are good tools, I have not found them able to do what I need so I am looking for a way to reduce manual work to a minimum by deleting duplicates from the second dir structure. I will have to sort/merge the remaining files by hand.
The closest to doing that is with fslint's findup (Linux.com :: Tidy up your filesystem with FSlint) which returns a list of duplicate files separated by empty lines.
Since the duplicates listed may also be within a single one of the directory structures, I cannot be sure to delete files that are also present in path 1.
I can't make myself really clear, I'm afraid, so here's an example:

dir1/path/dup1
dir2/somepath/dup1 <-- delete
dir2/path/to/dup1 <-- delete

One attempt may be to first delete duplicates from dir2 and afterwards compare with dir1.

Any help appreciated!

msguniq

MSGUNIQ(1)								GNU								MSGUNIQ(1)

NAME

       msguniq - unify duplicate translations in message catalog

SYNOPSIS

       msguniq [OPTION] [INPUTFILE]

DESCRIPTION

       Unifies duplicate translations in a translation catalog.  Finds duplicate translations of the same message ID.  Such duplicates are invalid
       input for other programs like msgfmt, msgmerge or msgcat.  By default, duplicates are merged together.  When using the  --repeated  option,
       only  duplicates  are  output,  and  all  other	messages are discarded.  Comments and extracted comments will be cumulated, except that if
       --use-first is specified, they will be taken from the first translation.  File positions  will  be  cumulated.	When  using  the  --unique
       option, duplicates are discarded.

       Mandatory arguments to long options are mandatory for short options too.

   Input file location:
       INPUTFILE
	      input PO file

       -D, --directory=DIRECTORY
	      add DIRECTORY to list for input files search

       If no input file is given or if it is -, standard input is read.

   Output file location:
       -o, --output-file=FILE
	      write output to specified file

       The results are written to standard output if no output file is specified or if it is -.

   Message selection:
       -d, --repeated
	      print only duplicates

       -u, --unique
	      print only unique messages, discard duplicates

   Output details:
       -t, --to-code=NAME
	      encoding for output

       --use-first
	      use first available translation for each message, don't merge several translations

       -e, --no-escape
	      do not use C escapes in output (default)

       -E, --escape
	      use C escapes in output, no extended chars

       --force-po
	      write PO file even if empty

       -i, --indent

       --no-location

       -w, --width=NUMBER

       -s, --sort-output
	      generate sorted output

       -F, --sort-by-file
