Move images from sub-folders into new sub-folders

  • 772

I have a folder composed of M several sub-folders, each of them containing some text files and N images (*.png)

This is what the tree looks like:

/parent/
  /sub-folder1/
   /data1.dat
   /data2.dat
   /image1.png
   /image2.png
   ...
   /imageN.png
 /sub-folder2/
   /data1.dat
   /data2.dat
   /image1.png
   /image2.png
   ...
   /imageN.png
 ...
 /sub-folderM/
   /data1.dat
   /data2.dat
   /image1.png
   /image2.png
   ...
   /imageN.png

notice that all images in each sub-folder are named the same (ie: image1.png, ..., imageN.png)

What I need is to move only the images into a new parent folder (say parent2), while replicating the sub-folder structure. After the moving is done the new parent folder should look like this:

/parent2/
  /sub-folder1/
   /image1.png
   /image2.png
   ...
   /imageN.png
 /sub-folder2/
   /image1.png
   /image2.png
   ...
   /imageN.png
 ...
 /sub-folderM/
   /image1.png
   /image2.png
   ...
   /imageN.png

(ie: only images and respecting the same sub-folders structure)

and the original parent folder should look like:

/parent/
  /sub-folder1/
   /data1.dat
   /data2.dat
 /sub-folder2/
   /data1.dat
   /data2.dat
 ...
 /sub-folderM/
   /data1.dat
   /data2.dat

(ie: images moved out)

I've seen some examples of scripts that can move all filed into a new folder (Shell script to move all files from subfolders to parent folder) or some that can move only images (Script to move pictures) but I haven't found one that would do so while respecting the sub-folders tree.

    You can try using rsync:

    rsync -av --include="*/"  --include='*.png' --exclude='*' parent1 parent2

    this creates directory parent2 and copies all files with .png extension with subdirectory structure to it.
    explanation

    • -v verbose to see whats copied
    • -a archive mode (copy subdirectories with same ownership, permissions etc.)
    • --include '*/' --include='*.png' include .png ending files first part is to create subdirectories
    • --exclude='*' exclude all other files for more info see rsync man page

    1. Copy parent1 to parent2
    2. Remove dat files from parent2 subdirectories
    3. Remove png files from parent1 subdirectories
    $ cp -r parent1/ parent2
$ rm parent2/*/*.dat
$ rm parent1/*/*.png
