I want to list the size of directories under a given root (using du -hs) . The issue is that where the directory names have spaces the du command is getting each word of the name as a whole directory name.

I tried to fix this by quoting the output through xargs but the output is the same.

#!/bin/bash

root="$1"
echo "Searching in $root"
for d in $(find $root -maxdepth 1 -type d | xargs -i echo "'{}'")
  do 
    #
    # the root directory can take a long time so let's skip it
    #
    if [ "$d" != "$root" ] 
      then
         echo "Looking at directory $d"
         echo $(du -hs "$d")
      fi
  done

    You don't want to remove the spaces if they're part of the filenames. The result would be a different filename. Instead you want to keep the filenames intact, but separate. But the thing is that the shell doesn't make it too easy to do that the way you hope to do it. Some mandatory reading linked. – ilkkachu Jul 30 '21 at 14:40
  • @ilkkachu Exactly. I thought I was doing that with '{}'. Guess not. I was not trying to remove the spaces. – Stephen Boston Jul 30 '21 at 17:01

Because of exactly the issue you describe, it is disrecommended to iterate over the output of find. Instead, you should use the -exec option if that is available to your version of find:

find "$root" -maxdepth 1 -type d -exec du -hs {} \;

To exclude the $root directory, you can add mindepth:

find "$root" -mindepth 1 -maxdepth 1 -type d -exec du -hs {} \;
