linux - Finding and counting duplicate filenames -

need search through sub folders of current folder recursively , list files of type , number of duplicates

e.g. if current folder home , there 2 sub folders dir1 , dir2 need search dir1 , dir2 , list file names , number of duplicates

this have far: using

find -name "*.h" . 

to list of files of type. need count duplicates , create new list like

 file1.h 2   file2.h 1 

where file1 file name , 2 number of duplicates overall.

use uniq --count

you can use set of core utilities quickly. example, given following setup:

mkdir -p foo/{bar,baz} touch foo/bar/file{1,2}.h touch foo/baz/file{2,3}.h 

you can find (and count) files pipeline this:

find foo -name \*.h -print0 | xargs -0n1 basename | sort | uniq -c 

this results in following output:

    1 file1.h     2 file2.h     1 file3.h 

if want other output formats, or order list in other way alphabetically file, can extend pipeline sort (e.g. sort -nr) or reformat columns sed, awk, perl, ruby, or text-munging language of choice.
