comparing content of two folders including all subfolders

[julien-1993]

Hi there,
I am facing a situation where I have 2 folders containing thousands of jpeg pictures.

One of them is a prior attempt of me to classified the content of the one that has all the pictures.
To summarize i have lets say folder A that contain 5000 pictures in a lot of sub-folder and sub-sub-folder and i have Folder B that contains about 3000 picture copied from folder A but nicely classified under appropriate sub-folder.

I am looking for a convenient way to compare the content of folder A and B (looking in all the sub-folders of course) and offer me the possibility to copy the file that are in A and not B to another directory to continue my classification.

thank you very much
a guy that is lost in the folders

edit: of course all files have different names, which is the sequence number the camera gives them

In KDE there's Komparator, not sure how in Gnome.

I figure this is something i've either needed to do before or surely will, so I whipped up a little python script. You might try setting up a few test folders with just a few images before running it on the whole shebang :)

It assumes your folders are "Photos" , "Photos-Sorted" , and "SortThese". Save this script in your home directory as "photosorter.py" and run it from the terminal like this:



python photosorter.py




import os

SortingDirectory = "SortThese"
DirectoryA = "Photos"
DirectoryB = "Photos-Sorted"


# A function to tell if a file counts as an image, by extension
def IsImage(f):
(shortname,ext) = os.path.splitext(f)
if ext in ('.jpg','.JPG','nef','.NEF','.JPEG','.jpeg'):
return True
else:
return False


# main program starts here

treelist1 = {}
treelist1[DirectoryA]=[]

fin,fout = os.popen4 ("ls -R1 " + DirectoryA)
filelist1=fout.read()
files1 = filelist1.splitlines()

fin,fout = os.popen4 ("ls -R1 " + DirectoryB)
filelist2=fout.read()
files2 = filelist2.splitlines()

curdir=DirectoryA

for f in files1:
if '/' in f:
curdir=f
curdir=curdir.rstrip(':')
treelist1[curdir]=[]
else:
# only add files with matching extensions
if IsImage(f):
treelist1[curdir].append(f)


print "Files that are in Photos and not in Photos-Sorted"
for d in treelist1:
for f in treelist1[d]:
if not f in files2:
print f

# do the same traversal, but copy them
for d in treelist1:
for f in treelist1[d]:
if not f in files2:
cmd='cp "' + d + '/' + f + '" ' + SortingDirectory
os.system(cmd)
