I found this script by Bruno that flattens a directory. Can someone tell me how to modify it to run it as loop so it would work on all directories within a specified (higher level) directory?
Thank you in advance ;)

# This scripts flattens the file directory
# Run this script with a folder as parameter:
# $ path/to/script path/to/folder


    local DIR="$1"
    for dir in "$DIR"/*/
        [ -d "${dir}" ] || continue # if not a directory, skip
        if [ "$(ls -A "$dir")" ]; then
            rmEmptyDirs "$dir"
            rmdir "$dir"
    done }

    local DIR="$1"
    find "$DIR" -mindepth 2 -type f -exec mv -i '{}' "$DIR" ';' }

flattenDir "$1" rmEmptyDirs "$1" echo "Done"

Just one line will move all files (in child subdirs) to pwd.

$ find  . -mindepth 2 -type f -exec mv {} .. \;

This will move all regular files including dot-files (start with a dot) but not links.

Then, remove empty dirs:

$ find . -type d -empty -delete

Whatever is left out contains links (or other types of files) not moved.


One way to perform a certain operation all directories found within a given directory, is

setopt -s nullglob
  setopt -u nullglob
  [[ -d $e ]] && YOUR_SCRIPT "$e"

Note that this will skip directories where the name starts with a dot. This is usually what we want, but if you want to include those directories as well, you can adapt my solution to this case too: See the dotglob option in the man page, and don't forget to exclude the special directories . and ...

Another possibilitiy is to use something like

find SPECIFIED_DIRECTORY -maxdepth 1 -type d -exec YOUR_SCRIPT {} \;
  • Thank you user1934428. How would I change your script to run YOUR script in CURRENT directory instead SPECIFIED_DIRECTORY? – Steven D Jul 4 '18 at 15:33
  • The current directory (I guess you mean: working directory) can be denoted by a single period (.) or by using the shell variable PWD ($PWD). – user1934428 Jul 9 '18 at 11:25
