`ddrescue` a directory

README.md

ddrfind - ddrescue on a directory

A non-recursive approach to using ddrescue on a directory.

Chances are, if you have a currupted set of memory, it's not just a few files. It's probably a whole disk. Wanna save it? You can use ddrescue, but that doesn't work on directories, only files. If you want to use it on a whole big directory, you'll need to do each file one by one. That's exactly what this script does.

Installation

$ fish ddrfind.fish

ddrfind.fish

function ddrfind --description 'ddrescue on a directory (using find)'
  if not test -d $argv[1]; or set -q $argv[2]
    echo "Usage: ddrfind <input-dir> <output-dir>"
    exit 1
  end

  set -l dest (pwd)"/"$argv[2]

  mkdir -p $dest

  cd $argv[1]
  for file in (find . -name "*")
    if test -d $file
      # make a new sub-directory
      mkdir -p $dest"/"$file
    else
      # rescue the file
      echo $dest"/"$file
      ddrescue $file $dest"/"$file > /dev/null
    end
  end
  cd -
end

Thank you so much, it works! I was trying to get this working for hours now before bothering someone else.
