-Usage: $0 [-r] [-v] directory [directory ...]
-
-Scans each directory and:
- 1) removes orphaned .AppleDouble files (from <directory>/.AppleDouble)
- 2) fixes permissions on .AppleDouble files to match corresponding data file (minus x bits)
- 3) fixes owner/group of .AppleDouble files to match corresponding data file (root only)
-
-Options:
- -r Recursively check all subdirectories of each directory
- -R Like -r but follows symbolic links to directories (warning: no loop-checking is done)
- -p Preview: no deletions or changes are actually made
- -v Verbose
