NAME

mount_hfs — mount an HFS+ file system

SYNOPSIS

DESCRIPTION

The mount_hfs command attaches the HFS file system residing on the device special to the global file system namespace at the location indicated by directory. This command is normally executed by mount(8) at boot time.

The options are as follows:

-u user

Set the owner of the files in the file system to user. The default owner is the owner of the directory on which the file system is being mounted. The user may be a user-name, or a numeric value.

-g group

Set the group of the files in the file system to group. The default group is the group of the directory on which the file system is being mounted. The group may be a group-name, or a numeric value.

-m mask

Specify the maximum file permissions for files in the file system. (For example, a mask of 755 specifies that, by default, the owner should have read, write, and execute permissions for files, but others should only have read and execute permissions. See chmod(1) for more information about octal file modes.) Only the nine low-order bits of mask are used. The default mask is taken from the directory on which the file system is being mounted.

-o

Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings.

-j

Ignore the journal for this mount.

-c

Disable group commit for journaling.

BUGS

Some HFS file systems with highly fragmented catalog files may not mount.

HISTORY

The mount_hfs utility first appeared in Mac OS X Server 1.0. As of Mac OS X 10.15, this utility will no longer mount HFS standard file systems.
