NAME
apple_dump - Dump AppleSingle/AppleDouble format file SYNOPSIS
apple_dump [-a] FILE | DIR apple_dump -f FILE apple_dump -d FILE apple_dump -h | -help | --help apple_dump -v | -version | --version DESCRIPTION
apple_dump dump AppleSingle/AppleDouble format file. OPTIONS
-a FILE|DIR This is default. Dump a AppleSingle/AppleDouble file for FILE or DIR automatically. Extrapolate FinderInfo type from absolute path. If FILE is not AppleSingle/AppleDouble format, look for .AppleDouble/FILE and ._FILE. If DIR, look for DIR/.AppleDouble/.Parent and ._DIR. -f FILE Dump FILE. Assume FinderInfo to be FileInfo. -d FILE Dump FILE. Assume FinderInfo to be DirInfo. -h, -help, --help Display the help and exit -v, -version, --version Show version and exit NOTE
There is no way to detect whether FinderInfo is FileInfo or DirInfo. By default, apple_dump examins whether file or directory, a parent directory is .AppleDouble, filename is ._*, filename is .Parent, and so on. If setting option -f or -d, assume FinderInfo and doesn't look for another file. SEE ALSO
