dot_clean

DOT_CLEAN(1)						    BSD General Commands Manual 					      DOT_CLEAN(1)

NAME

     dot_clean -- Merge ._* files with corresponding native files.

SYNOPSIS

     dot_clean [-fmnsv] [--keep=[mostrecent|dotbar|native]] [dir ...]

DESCRIPTION

     For each dir, dot_clean recursively merges all ._* files with their corresponding native files according to the rules specified with the
     given arguments.  By default, if there is an attribute on the native file that is also present in the ._ file, the most recent attribute will
     be used.

     If no operands are given, a usage message is output.  If more than one directory is given, directories are merged in the order in which they
     are specified.

OPTIONS

     -f      Flat merge.  Do not recursively merge all directories in the given dir.  This is off by default.

     -h      Help. Prints verbose usage message.

     -m      Always delete dot underbar files.

     -n      Delete dot underbar file if there is no matching native file.

     -s      Follow symbolic links.  This will follow symbolic dot underbar files when they are found.

     -v      Print verbose output.

     --keep=mostrecent
	     The default option.  If an attribute is associated with a data fork, use that.  Otherwise, use information stored in the AppleDouble
	     file.  Note that the native fork's data is preferred even if the data in the AppleDouble file is newer.

     --keep=dotbar
	     Always use information stored in the AppleDouble file, replacing any extended attributes associated with the native file.

     --keep=native
	     Always use the information associated with the data fork, ignoring any AppleDouble files.

EXAMPLES

     The following is how to do an dot_clean merge on the mounted volume test, always using the dot underbar information.

	   dot_clean --keep=dotbar /Volumes/test

DIAGNOSTICS

     The dot_clean utility exits 0 on success, and >0 if an error occurs.

BUGS

     None known.
