Hello all,
I have a file containing multiple filenames.

Sample format: 
This/is/the/full/path/file.abc.part-1.txt
This/is/the/full/path/file.abc.part-2.txt
This/is/the/full/path/file.abc.part-3.txt
This/is/the/full/path/file.def.part-1.txt
This/is/the/full/path/file.def.part-2.txt
This/is/the/full/path/file.ghi.part-1.txt
This/is/the/full/path/file.jkl.part-2.txt
This/is/the/full/path/file.mno.part-5.txt

[download]
I want to concatenate files that have the same name. For eg.
This/is/the/full/path/file.abc.part-1.txt This/is/the/full/path/file.abc.part-2.txt This/is/the/full/path/file.abc.part-3.txt
These 3 files should be appended together into a file named: This/is/the/full/path/file.abc.MERGED.txt
I think I should split at the . but how to compare between abc and def to put them in different files?
Thank you all in advance.
