NAME

       mount_hsfs - mount hsfs file systems

SYNOPSIS

       mount -F hsfs [generic_options] [-o FSType-specific_options] [-O ]  special | mount_point

       mount -F hsfs [generic_options] [-o FSType-specific_options] [-O] special mount_point

DESCRIPTION

       mount attaches a  High Sierra file system  (hsfs) to the file system hierarchy at the mount_point, which is the pathname of a directory. If
       mount_point has any contents prior to the mount operation, these are hidden until the file system is unmounted.

       If  mount is invoked with  special or  mount_point as the only arguments,  mount will search  /etc/vfstab to fill in the missing arguments,
       including the  FSType-specific_options; see mount(1M) for more details.

       If  the	file  system being mounted contains Rock Ridge extensions, by default they will be used, enabling support of features not normally
       available under High Sierra file systems such as symbolic links, and special files.

OPTIONS

       generic_options

	   See mount(1M) for the list of supported options.

       -o

	   Specify  hsfs file system specific options.	If invalid options are specified, a warning message is printed and the invalid options are
	   ignored. The following options are available:

	   global |  noglobal

	       If  global  is specified and supported on the file system, and the system in question is part of a cluster, the file system will be
	       globally visible on all nodes of the cluster. If noglobal is specified, the mount will not be globally visible. The default  behav-
	       ior is noglobal.

	   ro

	       Mount the file system read-only.  This option is required.

	   nrr

	       no  Rock  Ridge:  if Rock Ridge extensions are present in the file system, ignore them; interpret it  as a regular High Sierra file
	       system.

	   notraildot

	       File names on High Sierra file systems consist of a proper name and an extension separated by a '.' (dot) character.   By  default,
	       the  separating	dot  is  always  considered  part of the file's name for all file access operations, even if there is no extension
	       present. Specifying  notraildot makes it optional to specify the trailing dot to access a file whose name lacks an extension.

	       Exceptions: This option is effective only on file systems for which Rock Ridge extensions are not active, either because  they  are
	       not  present  on  the CD-ROM, or they are explicitly ignored via the nrr option. If Rock Ridge extensions are active,  hsfs quietly
	       ignores this option.

	   nomaplcase

	       File names on High Sierra cdroms with no Rock Ridge extensions present should be uppercase characters only. By default,	hsfs  maps
	       file  names  read  from	a  non-Rock  Ridge disk to all lowercase characters. nomaplcase turns off this mapping. The exceptions for
	       notraildot discused above apply to  nomaplcase.

       -O

	   Overlay mount.  Allow the file system to be mounted over an existing mount point, making the underlying file system inaccessible.  If a
	   mount is attempted on a pre-existing mount point without setting this flag, the mount will fail, producing the error device busy.

FILES

       /etc/mnttab     table of mounted file systems

       /etc/vfstab     list of default parameters for each file system

NOTES

       If  the directory on which a file system is to be mounted is a symbolic link, the file system is mounted on the directory to which the sym-
       bolic link refers, rather than on top of the symbolic link itself.
