apple_dump

APPLE_DUMP(1)							   Netatalk 2.2 						     APPLE_DUMP(1)

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.
