NAME
mount, umount (generic) - mount or unmount file systems and
remote resources
SYNOPSIS
mount [-v |-p]
mount [-F FSType] [-V] [current_options] [-o
specific_options] {special | mount_point}
mount [-F FSType] [-V] [current_options] [-o
specific_options] special mount_point
umount [-V] [-o specific_options] {special | mount_point}
DESCRIPTION
File systems other than root ( / ) are considered removable
in the sense that they can be either available to users or
unavailable. mount notifies the system that special, a
block special device or a remote resource, is available to
users from the mount_point which must already exist; it
becomes the name of the root of the newly mounted special or
resource.
mount, when entered with arguments, validates all arguments
except for the device name and invokes a FSType specific
mount module. If invoked with no arguments, mount lists all
the mounted file systems from the mount table. If invoked
with any of the following partial argument lists, for exam-
ple, one of special or mount_point or when both arguments
are specified but no FSType is specified mount will search
/etc/vfstab to fill in the missing arguments: FSType, spe-
cial, mount_point, and specific_options. It will then
invoke the FSType-specific mount module.
Most FSTypes do not have a umount specific module. If one
exists it is executed otherwise the generic unmounts the
file systems. If the -o option is specified the umount
specific module is always executed.
current_options are options supported by the s5-specific
module of mount and umount. Other FSTypes do not neces-
sarily support these options. specific_options indicate
suboptions specified in a comma-separated list of suboptions
and/or keyword-attribute pairs for interpretation by the
FSType-specific module of the command.
The options are:
-v Print the output in a new style. The new output
has the FSType and flags displayed in addition to
the old output. The mount_point and special
fields are reversed.
-p Print the list of mounted file systems in the

/etc/vfstab format.
-F used to specify the FSType on which to operate.
The FSType must be specified or must be determin-
able from /etc/vfstab while mounting a file sys-
tem.
-V Echo the complete command line, but do not execute
the command. The command line is generated by
using the options and arguments provided by the
user and adding to them information derived from
/etc/vfstab. This option should be used to verify
and validate the command line.
-o used to specify FSType-specific options.
mount can be used by any user to list mounted file systems
and resources. Only a super-user can mount or unmount file
systems.
NOTES
The old output format will be phased out in a future release
and all output will be in the new -v format. The most signi-
ficant changes are the addition of two new fields to show
the FSType and flags and the reversal of the mount_point and
special name.
mount adds an entry to the mount table /etc/mnttab; umount
removes an entry from the table.
